Liver Cancer - Incidence, Symptoms, Causation, Treatment and Prognosis

By : Dick Aronson

Liver cancer also known as primary or metastatic hepatic carcinoma is a fairly rare form of cancer in the western world (1% of all cancers) but much more common in Africa and parts of Asia (10% to 50% of all cancers).It is much more prevalent in men and incidence increases with age. Liver cancer is rapidly fatal, usually within 6 months from gastrointestinal hemorrhage, hepatic failure or metastasis.

TYPES OF LIVE CANCER
Most primary liver tumors are known as hepatomas (hepatocellular carcinoma and primary lower cell carcinoma). Some primary liver cancers originate in the bile duct and these are known as cholangiomas.Some rare liver cancers include Kupffer cell sarcoma and hepatoblastomas (which occur almost exclusively in children and are usually respectable and curable). Metastatic liver cancer is 20 times more common than primary liver cancer and after cirrhosis this is the leading form of liver related death.

SIGNS AND SYMPTOMS
Liver cancer does not normally cause symptoms until it is in an advanced stage.
Clinical effects of advanced liver cancers include:
1. A mass in the right upper side.
2. Tender, nodular liver on palpation
3. Severe pain in the epigastrium or upper right side
4. Weight loss, anorexia, weakness, fever
5. Occasional jaundice or ascites (fluid in the abdomen)

CAUSATION
The exact cause of liver cancer is unknown in adults but in children it may be a genetic disease. Adult liver carcinomas may result from environmental exposure to carcinogens such as mold, contrast media (no longer in use), androgens and oral estrogens, the hepatitis B virus or by damage to the liver due to cirrhosis caused by too much prolonged imbibing of alcohol.

DIAGNOSIS
Liver cancer is difficult to diagnose in the presence of cirrhosis, but several tests can help identify it: The combination of an imaging study (ultrasound, CT, or MRI scans) and an elevated blood level of alpha-fetoprotein will most effectively diagnose liver cancer, electrolyte studies may indicate increased sodium retention, a liver biopsy can make a definitive diagnosis.

TREATMENT
Treatments for primary liver cancer depend on the extent (stage) of the disease, age, overall health, feelings and personal preferences. Surgery is the most effective treatment for primary liver cancer, but this is not always possible due to the size or position of the tumor. Radiofrequency ablation is an option for people with small, unresectable hepatocellular tumors and for some types of metastatic liver cancers. During this procedure, the hepatic artery (the artery from which liver cancers derive their blood supply) is blocked, and chemotherapy drugs are injected between the blockage and the liver. Cryoablation may be an option for people with inoperable primary and metastatic liver cancers. Removing the whole liver and replacing it with a liver from another person is another possible form of treatment for primary liver cancer.

Even when treatments fail to provide much improvement in the liver cancer itself, pain and other signs and symptoms caused by liver cancer can be aggressively treated to improve quality of life. In general, the treatments available for children are the same as for adults, and the best approach depends on the stage and type of cancer as well as the child's age and overall health.

PROGNOSIS
Prognosis is poor when cancer is advanced, but for small tumors that are confined to the liver, ablative therapies are palliative and surgical resection or liver transplantation is sometimes curative.

Mesothelioma is a Deadly Cancer

By : April Kerr

Mesothelioma is considered to be the most deadly type of cancer that cannot be cured easily and the person who suffers from Mesothelioma do not survive for a long time as the lining of the internal organs like the heart, the lungs and the stomach is affected. This cancer is mainly caused by the exposure to asbestos or materials that contain asbestos. This cancer cannot be detected at an early stage as the symptoms of the disease can be seen only in the developed or the last stage. It is a malignant cancer that is the result of inhaling particles of damaged asbestos in the air which start damaging the lining of the internal organs.

Symptoms of Mesothelioma

The symptoms of Mesothelioma can be detected after 20 to 50 years of exposure. If the lining of the heart or the lungs is damaged then the most common problem that develops is breathing problem. This is due to the accumulation of fluid in the chest, which is known as Pleural Mesothelioma. The symptoms are totally different if the stomach lining is affected. The patient often complains of stomach ache, loses his appetite and other problems develop like problem in the bowel, frequent fever, anemia and other problems. Most of the people take these symptoms lightly and by the time they go to the doctor it is too late. After the disease is detected in most patients survive between 6 to 12 months.

Treatment for Mesothelioma

An effective treatment of this disease depends on several factors like, in which stage the cancer has been detected, what is the age of the patient, how much the cancerous cells have circulated and the general health condition of the patient, that is whether he is suffering from some other disease or not. It has been observed that chemotherapy is the only treatment available for these patients. It uses medicines, chemicals or drugs in a systematic manner to eradicate the cancerous cells. The medicine is either injected directly in the body or administered in pill forms.

In few cases the medicine is directly injected in chest. This is called intrapleural chemotherapy. If the lining of the stomach is affected then the medicine is inserted into the abdomen which is called intra peritoneal chemotherapy. The direct insertion is done to retard the formation of the cancerous cells. Patients are advised before the surgery and after the surgery to minimize the development of the cancerous cell.

The patient has to bear the pain of chemotherapy treatment to be cured and gain longevity or has to meet his end within 6-12 months. Now it is in the hands of the patient whether he will go for chemotherapy and have full faith of recovery.

Kids Who Whip Cancer Face Heart Risks

By : Gregory Smyth

It seems unfair, but it has recently been proven - children who survive cancer in early childhood go on to be at a hugely increased risk of heart disease. A 20-year study by the Childhood Cancer Survivor Study has recently been completed, and it has found that those who survived child cancer were up to 10 times more likely to have atherosclerosis, 6 times more likely to have heart failure, and 5 times more likely to have a heart attack than those who had a cancer-free childhood.

The study compared childhood cancer survivors, from as wide a variety of cancers as Hodgkin's disease, leukemia, brain tumors, kidney tumors, and lymphoma. It looked at the cancer survivors and their siblings, and found that, after 20 years, 2% of the cancer survivors had atherosclerosis, which was 10 times greater than their siblings, 4% of the survivors had congestive heart failure, which was 6 times the average in their siblings, and 5% of the survivors had a heart attack at some point, which was more than 5 times the number their siblings had. They were also found to have 6 times the number of cases of pericardial disease than their siblings, and 5 times the number of cases of valvular disease.

Even if the cancer survivors lead a healthier lifestyle, the increased risk still exists. They are said to be developing the sorts of disease that doctors normally only put on the radar for patients in their 40s and 50s. This means that cancer survivors need to be particularly aware of these risks, and let their doctors know their full medical history and the results of these findings, in order to help prevent any adverse effects from these heart diseases.

The reason that cancer survivors were fund to beat such a hugely increased risk of heart disease was because of the radiation and chemotherapy drugs used to treat the cancers. Radiation therapy kills off cancerous cells, and 'largely' leaves healthy tissue alone - but we all know that radiation can have varied and serious effects, and radiation therapy is no exception. One piece of good news with this though, is that as radiation therapy has been refined, it is now more targeted to the tumor and less likely to have adverse effects on the heart (unless, of course, the tumor is in close proximity to the heart).

Chemotherapy drugs are also touted as a cause of this increased risk of heart cancer in child cancer survivors. They have been found to damage the tissue of the heart - but unfortunately, as with radiation therapy, the techniques and drugs used today are largely the same as they were back in the 1970s, when the participants in this study were receiving their treatment.

The message of this article is not just doom and gloom for people who have already survived a great deal in their lives. It is important for these cancer survivors to realize that the impact of their childhood disease on their adult health can be reduced with regular checkups. Let your physician know that you are concerned about your heart health, and find out what tests you can regularly and safely undergo to screen you for early heart disease. You don't necessarily need to see an oncologist for the rest of your life - just keep your GP informed. Maintain your healthy diet and lifestyle, and keep in constant contact with the medical profession - they have saved you before, they can do it again!

Colon Cancer, Incidence, Causation, Diagnosis, Treatment and Prognosis

By : Dick Aronson

Colon cancer is cancer of the large intestine (colon), the lower part of your digestive system. Colon cancer is the second most common cancer in the USA with equal distribution between men and women. Colon cancer usually affects people over the age of 40, with the majority of people who are diagnosed with the condition being over 60 years of age. Colon cancer may affect any racial or ethnic group; however, some studies suggest that Americans of northern European heritage have a higher-than-average risk of colon cancer.

INCIDENCE
Colon cancer is more common in industrialized nations and in those societies where red meat is a major part of the diet, although evidence tends to suggest that merely changing your diet to white meat and seafood as in for instance Japan, tends to just swap stomach cancer for colon cancer. In almost all cases colon cancer is a treatable disease if caught early.

SIGNS AND SYMPTOMS
Colon cancer usually begins with the growth of benign growths such as polyps. Often there are no early symptoms. If signs and symptoms of colon cancer do appear, they may include: a change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool for more than a couple of weeks, rectal bleeding or blood in your stool, persistent abdominal discomfort, such as cramps, gas or pain, abdominal pain with a bowel movement, a feeling that your bowel doesn't empty completely, weakness or fatigue and unexplained weight loss.

CAUSES
Colon cancer's exact cause is unknown, but it appears to be influenced by both inherited and environmental factors. Studies show a concentration in areas of higher economic development suggesting a relationship to diet, particularly excess animal fat and low fiber. Other factors that increase the risk of developing colon cancer are: age over 40, the presence of other diseases of the digestive tract, family history and ulcerative colitis.
Development of colon cancer at an early age, or at multiple sites, or recurrent colon cancer, suggests a genetically transmitted form of the disease as opposed to the sporadic form. There also is a slight increased risk for colon cancer in the individual who smokes.
The most common colon cancer cell type is adenocarcinoma which accounts for 95% of cases.

DIAGNOSIS
The development of polyps of the colon usually precedes the development of colon cancer by five or more years. The American Gastroenterologial Association revised its screening guidelines in 2003 to recommend that people with two or more first-degree relatives with colorectal cancer or a first-degree relative with colon or rectal cancer before age 60 should have a screening colonoscopy beginning at age 40 or beginning 10 years prior to the age of the earlier colon cancer diagnosis in their family (whichever is earliest). Those with a first-degree relative diagnosed with colon cancer after age 60 or two second-degree relative with colon or rectal cancer should begin screening at age 40 with one of the methods listed above, such as annual sigmoidoscopy. The most common colon cancer screening tests are colonoscopy, sigmoidoscopy, and fecal occult blood test.
CT scans and Barium enemas are also routinely used for diagnosis of colon and rectal cancers.

TREATMENT
Almost all colon cancers are treated with surgery first, regardless of stage. The malignant tumor, adjacent tissues and any lymph nodes that may contain cancer cells are removed.
In colon cancer, chemotherapy after surgery is usually only given if the cancer has spread to the lymph nodes (Stage III). Radiation therapy may also be used to induce tumor regression. As with other cancer treatments, the incidence of side effects varies with patient health and the exact nature of the treatment.

PREVENTION
There is not an absolute method for preventing colon cancer. Still, there are steps an individual can take to dramatically lessen the risk or to identify the precursors of colon cancer so that it does not manifest itself. People who turn age 50, and all of those with a history of colon cancer in their families, should speak with their physicians about the most recent screening recommendations from physician and cancer organizations. They should watch for symptoms and attend all recommended screenings to increase the likelihood of catching colon cancer early. Exercise is believed to reduce the risk of colon cancer. Apparently, no association exists between frequency of bowel movement or laxative use and risk of colon cancer.

PROGNOSIS
Prognosis depends on the stage of the disease and the overall health of the patient. If diagnosed early, before the tumor has spread from the bowel, these treatments are very effective, with about 90% of patients alive five years after diagnosis. If the colon cancer does not come back (recur) within 5 years, it is considered cured. Prognosis is poor in patients with liver and lung metastases.

Lung Cancer, Causes, Diagnosis and Treatment

By : Dick Aronson

Lung cancer may be the most tragic cancer because in most cases, it might have been prevented, 87% of lung cancer cases are caused by smoking. Lung cancer has long been the most common cause of cancer death in men and since 1987 it has also become the most common cause of cancer death in women. Lung cancer is the second most commonly occurring form of cancer in most western countries and although the lung cancer incidence is less common in developing countries, the rapid increase in the popularity of smoking will see the number of lung cancer sufferers in those countries quickly catch up with the western world.

Lung cancers can arise in any part of the lung, and 90%-95% of cancers of the lung are thought to arise from the epithelial, or lining cells of the larger and smaller airways (bronchi and bronchioles); for this reason, lung cancers are sometimes called bronchogenic carcinomas or bronchogenic cancers.
The most common type of lung cancers are epidermoid carcinoma, small cell carcinoma, adenocarcinoma and large cell carcinoma.

Most experts agree that lung cancer is attributable to inhalation of carcinogenic pollutants by a susceptible host. Who is most susceptible? Any smoker over the age of 40, especially if they began smoking before the age of 15, have smoked 20 or more for 20 years, or worked with or near asbestos. Two other factors also increase susceptibility: exposure to carcinogenic industrial and air pollutants (asbestos, uranium, arsenic, nickel, iron oxides, chromium, radio active dust, and coal dust.) and familial susceptibility.

SIGNS AND SYMPTOMS
Because early lung cancer usually produces no symptoms, the disease is often in an advanced stage when first diagnosed. Late stage signs are: with epidermoid and small cell carcinoma; smokers cough, hoarseness, wheezing, dyspnea, hemoptysis and chest pain. With adenocarcinoma and large cell carcinoma; fever, weakness, weight loss, anorexia and shoulder pain. In addition, hormone production which regulates various body functions may also be affected.

DIAGNOSIS
Firm diagnosis requires chest x rays, sputum cytology, CT scanning, bronchoscopy the examination of pleural fluid and biopsies. Other tests to detect metastasis include bone scans, bone marrow biopsy and CT scans of the brain and abdomen.

METASTASES
Lung cancer most often spreads to the liver, the adrenal glands, the bones, and the brain. Lung cancer that has metastasized to the bone causes bone pain, usually in the backbone (vertebrae), the thighbones, and the ribs. Lung cancer that spreads to the brain can cause difficulties with vision and weakness on one side of the body.
Lung cancer may grow into certain nerves in the neck, causing a droopy eyelid, small pupil, sunken eye, and reduced perspiration on one side of the face; together these symptoms are called Horner's syndrome (see Autonomic Nervous System Disorders: Horner's Syndrome). Lung cancer may grow directly into the esophagus, or it may grow near it and put pressure on it, leading to difficulty in swallowing. Lung cancer may also spread through the bloodstream to the liver, brain, adrenal glands, spinal cord, and bone.

TREATMENT
Treatment for lung cancer depends on the cancer's specific cell type, how far it has spread, and the patient's performance status. If investigations confirm lung cancer, CT scan and often positron emission tomography (PET) are used to determine whether the disease is localised and amenable to surgery or whether it has spread to the point where it cannot be cured surgically. Treatment is usually a combination of surgery, chemotherapy and radiation therapy.

Surgery is usually the first option. Chemotherapy can be used as a first line treatment for lung cancer or as additional treatment after surgery. Radiation therapy can be directed at your lung cancer from outside your body (external beam radiation) or it can be put inside needles, seeds or catheters and placed inside your body near the cancer (brachytherapy). Radiation therapy can be used alone or along with other lung cancer treatments. Radiation therapy can also be used to lessen side effects of lung cancer.

Treatment may not be as effective for patients with bone or liver metastases from lung cancer, excessive weight loss, ongoing cigarette use, or pre-existing medical conditions such as heart disease or emphysema. At some point, if you and your oncologist or primary care physician agree that treatment no longer is advisable, hospice care can provide comfort.

How Asbestos Can Destroy Your Life

By : Joaquin Costa

Lung cancer is the fastest growing cancer in the world. In the USA we have seen many cases of asbestos that are simply destroying entire families. Not only in states with a huge history in the construction industry, have show thousands of cases of asbestos victims, but over the last 15 years, mortality from lung cancer has more than tripled.

One of the most dramatic and serious problems with lung cancer is the most common and take 15 to 20 years to develop after exposure. Asbestosis, or scarring of the lung tissue, also takes 15 to 20 years to appear. This means that when asbestos starts to reveals it's presence the people responsible of the damages based on asbestos may be already out of business or not even alive.

Althoug many companies are already aware of the dangers of asbestos, removing asbestos from older buildings is a difficult, dangerous and expensive process, and clearly not a job for amateurs. There is good reason for all these precautions. Removing asbestos from public buildings must be done by a licensed contractor who is registered with the state. Obviously this sort of rules and conditions in the law, change of each states in the USA.

So why do we still have buildings with asbestos? Well, the main reason is that depending on the extent of the work, removing or abating asbestos in a public building can run into hundreds of thousands or even millions of dollars, a very, very expensive kind of work for any company to afford.

In all the parts of the US, building owners are required to perform in-depth surveys of their property and report to the construction inspectors. If asbestos qualifies for removal, the building owner must contact and hire an authorized asbestos removal company, which will take care of this dangerous quemical, including removing it, transporting it and destoying it.

In many cases if buildings are going to be destroyed, there are not allowed to to be demolished if there is friable asbestos present. Also, any sort of schools or educational center are required by AHERA, the Asbestos Hazard Emergency Response Act, to be inspected and have a management plan prepared, which is to be maintained and available for public inspection.

Now the interesting thing is how health experts are so keen in having different points regarding asbestos. According to an university research , 2.3 of every 98,000 people living in buildings made from cement containing asbestos are liable to develop lung cancer. And it has been proved that health damage due to exposure to asbestos will certainly increase rapidly in the coming months and years. Healthcare maintenance workers and engineers can be unknowingly exposed to asbestos from many possible areas and sources.

Engineers can be exposed while working in furnace rooms where boilers are insulated with asbestos, or when making repairs to old piping or doing minor renovations.

Asbestos is commonly found in ultramafic rock, including serpentine, and near fault zones. The amount of asbestos that is typically present in these rocks can be usually less than 1% up to the high level 30%. So how really asbestos arrives to our lungs? Well, asbestos fibers can be released into the air when asbestos materials are destroyed. Objects with asbestos that remain in one piece represent little or no risk for our health.

Breast Cancer - Diagnosis,Causes, Symptoms,Treatments,Prognosis

By : Dick Aronson

Breast cancer is the most common cancer in women affecting one in eight women during their lives. It may develop at any time but the risk of developing it increases as women get older. It is far more common in post-menopausal women and the risk continues to increase with rising age.

CAUSE
The cause of breast cancer is not known and while it can also occur in men, the much higher occurrence in women implicates estrogen.
Today, breast cancer, like other forms of cancer, is considered to be the final outcome of multiple environmental and hereditary factors.

Breathing secondhand smoke increases breast cancer risk by 70% in younger, primarily pre-menopausal women.
A newly released study indicates a correlation between the drop in breast cancer and the drop in women taking HRT.

SIGNS AND SYMPTOMS
Breast cancer elicits so many fears, including those relating to surgery, death, loss of body image and loss of sexuality, however it is more easily treated and often curable if it is found early, therefore regular self examination and screening is essential. Breast cancer usually shows as a lump or thickening in the breast tissue, although most breast lumps are not cancerous.

Certain predisposing factors are clear.
Women at high risk are those who:
Have a family history of breast cancer.
Have long menstrual cycles, began menses early or menopause late.
Have never been pregnant
Were first pregnant after age 31.
Have had unilateral breast cancer.
Have endometrial or Ovarian cancer.
Were exposed to low level ionizing radiation.
Many other possible factors are still under investigation including, obesity, alcohol and environmental factors.

Those with lower risk include women who:
Were pregnant before age 20.
Have had multiple pregnancies.
Are native American or Asian.

Breast cancer occurs more often in the left breast and in the upper quadrant.
Indications of breast cancer other than a lump may include changes in breast size or shape, skin dimpling, nipple inversion, or spontaneous single-nipple discharge.

TYPES
When breast cancer cells invade the dermal lymphatics, small lymph vessels in the skin of the breast, its presentation can resemble skin inflammation and thus is known as inflammatory breast cancer (IBC). Symptoms of inflammatory breast cancer include pain, swelling, warmth and redness throughout the breast, as well as an orange peel texture to the skin referred to as peau d'orange.

The most common pathologic types of breast cancer are invasive ductal carcinoma, malignant cancer in the breast's ducts, and invasive lobular carcinoma, malignant cancer in the breast's lobules.
Occasionally, breast cancer presents as metastatic disease, that is, cancer that has spread beyond the original organ. Bone or joint pains can sometimes be manifestations of metastatic breast cancer, as can jaundice or neurological symptoms.

TREATMENT
Much controversy still exists over treatment of breast cancer, options include; Surgery , chemotherapy, Radiotherapy,Hormonal therapies,Herceptin and complementary treatments.

The mainstay of breast cancer treatment is surgery when the tumor is localized, with possible adjuvant hormonal therapy (with tamoxifen or an aromatase inhibitor), chemotherapy, and/or radiotherapy.

In February 2007, the MammaPrint test became the first breast cancer predictor to win formal approval from the Food and Drug Administration. This is a new gene test to help predict whether women with early-stage breast cancer will relapse in 5 or 10 years, this could help influence how aggressively the initial tumor is treated.

Interstitial laser thermotherapy (ILT) is an innovative method of treating breast cancer in a minimally invasive manner and without the need for surgical removal, and with the absence of any adverse effect on the health and survival of the patient during intermediate follow up.

PREVENTION
Routine (annual) mammography of women older than age 40 or 50 is recommended by numerous organizations as a screening method to diagnose early breast cancer and has demonstrated a protective effect in multiple clinical trials.
Women with one or more first-degree relatives (mother, sister, daughter) with premenopausal breast cancer should begin screening at an earlier age.

PROGNOSIS
There are many prognostic factors associated with breast cancer: staging, tumour size and location, grade, whether disease is systemic (has metastasized, or traveled to other parts of the body), recurrence of the disease, and age of patient.

With advances in screening, diagnosis, and treatment, the death rate for breast cancer has declined by about 20% over the past decade, and research is ongoing to develop even more effective screening and treatment programs.

My Full Exposure on Cancer

By : Uchenna Ani-Okoye

The body is equipped to deal with cancer. Women who have their ovaries removed at an early age rarely get breast cancer. The reasons one of the reasons cancer is so feared is because it is one of the least understood diseases.

They are also 55 percent more likely to develop the most deadly form of skin cancer, malignant melanoma, which can spread into the lymph system, bones and the organs. As with any cancer, the outcome is always better if it is caught early. In the case of limited stage SCLC, radiation therapy may also be used as the cancer is still localized to the chest area where radiation can be focused.

Prostate cancer usually exhibits no symptoms and the only way it can be detected is through a rectal prostate exam or a blood PSA screening. The cancer cells are still contained within the breast duct, but they have been programmed to grow much faster because of the over expression of such oncogene.

However, on their website, the Cancer Center states that data from an observational study done in China in 1994 suggest that Lycium polysaccharides have positive effects when used with certain cancer treatments.

Smoking can also increase your risk for cancer. This tree contains most of the vitamins, minerals, and other essential nutrients your body needs to function properly and fight off cancer. One of the reasons that the Mediterranean diet lowers the incidence of cancer is found in the fact that the diet is rich in whole grains and dietary fibre.

Death from cancer is exceeded only by heart disease. The Block Center for Integrative Cancer Care and Optimal Health was founded in 1980 by Penny and Keith Block, M. Let's begin by reviewing the way cancer is treated in North America, the UK and most "developed" countries today.

Smoking also increases the risk of other cancers, including breast, uterine cancer, bladder and oral cancer. Again, from Lance Armstrong: What surviving cancer teaches you is the magnitude of your dependence on others, not just for self-definition, but for your mere existence. There is a direct correlation between physical activity on that home gym equipment and a lowered risk of diabetes, heart disease, high blood pressure, colon cancer, and muscle, bone and joint problems.

Due to the advance of science in this day & age this link can be proven, with overwhelming evidence that people who lead active lifestyles are less likely to die early or to experience major illnesses such as heart disease, diabetes & colon cancer. This year, about 1,200,000 new cancer cases will be diagnosed in the USA alone, with hundreds of thousands more in the UK and in Australia and other Western countries. Trans-fatty acids are associated with heart disease, breast cancer, and diabetes.

Beta-carotene reduces the risk of bladder, lung, breast, and stomach cancers, heart disease, and slows down the development of arthritis. Another way oolong tea may help fight cancer is through preventing cell mutation. Personalities the positive side of cancer: The Cancerian's most positive point is his understanding nature.

Anderson Cancer Center in Houston, Texas as a Community Clinical Oncology Program (CCOP) and is also engaged in clinical cancer research with other university facilities in the United States and Israel.

Because of the latency in prostate cancer symptoms, it is important that men take preventative measures starting at around age 30. People with HIV who participated in massage studies showed an increased number of natural killer cells, which are thought to defend the body from viral and cancer cells..by the errors that can occur in the production of a lymphocyte.

Researchers in India discovered a link between the rise in carbonation consumption and esophageal cancer in America over the past two decades.

An Overview of Cancer

By : Dick Aronson

Cancer is second only to cardiovascular disease as the leading cause of death in the Western world.
Although Cancer is primarily a disease of the elderly with more than 60% of deaths from cancer occurring in those over the age of 65, cancer can strike even the youngest of children.

Cancer appears to occur when the growth of cells in the body is out of control and cells divide too rapidly. Cancer can develop in almost any organ or tissue, such as the lung, colon, breast, skin, bones, or nerve tissue.

Most common sites are:
Prostrate 24%
Breast 13%
Lung 13%
Colon and Rectum 9%
Bladder 3%
Uterus 2.5%

The cause of Cancer is believed to be a combination of genetic factors and outside carcinogens such as tobacco, viruses, infection, asbestos, vinyl chloride, inappropriate diet.

Cancer often has no specific symptoms, so it is important that you limit your risk factors and undergo appropriate cancer screening. The signs and symptoms will depend on where the cancer is, the size of the cancer, and how much it affects the nearby organs or structures.

If a cancer spreads (metastasizes), then symptoms may appear in different parts of the body. As a cancer grows, it begins to push on nearby organs, blood vessels, and nerves. If the cancer is in a critical area, such as certain parts of the brain, even the smallest tumor can cause early symptoms.

But sometimes cancers start in places where it does not cause any symptoms until the cancer has grown quite large. Pancreatic cancers, for example, do not usually grow large enough to be felt from the outside of the body.
By the time a pancreatic cancer causes these signs or symptoms, it has usually reached an advanced stage.

A cancer may also cause symptoms common to many other problems, such as; fever, fatigue and weight loss. This may be because the cancer uses up much of the body s energy or it may cause the release of substances which affect metabolism.

Some lung cancers make hormone-like substances that affect blood calcium levels, affecting nerves and muscles and causing weakness and dizziness.

It is important to know what some of the general (non-specific) signs and symptoms of cancer are, but remember that having any of these does not mean that you have cancer.

Most cancers can be treated and some cured, depending on the specific type, location, and stage. The earlier the cancer is found, the better the prognosis.

A good example of the importance of finding cancer early is melanoma skin cancer. Skin cancer can be easy to remove if it has not grown deep into the skin, and the 5-year survival rate (percentage of people living at least 5 years after diagnosis) at this stage is nearly100%.

Screening for breast cancer with mammograms has been shown to reduce the average stage of diagnosis of breast cancer in a population.
Colorectal cancer can be detected through fecal occult blood testing and colonoscopy, which reduces both colon cancer incidence and mortality, presumably through the detection and removal of pre-malignant polyps.
Similarly, cervical cytology testing (using the Pap smear) leads to the identification and excision of precancerous lesions.
Testicular self-examination is recommended for men beginning at the age of 15 years to detect testicular cancer.

SIGNS and SYMPTOMS

Pain may be an early symptom with some cancers such as bone cancers or testicular cancer.

Long-term constipation, diarrhea, or a change in the size of the stool may be a sign of colon cancer.

Pain with urination, blood in the urine, or a change in bladder function (such as more frequent or less frequent urination) could be related to bladder or prostate cancer.

Skin cancers may bleed and look like sores that do not heal.

A long-lasting sore in the mouth could be an oral cancer and should be dealt with right away, especially in patients who smoke, chew tobacco, or frequently drink alcohol.

Sores on the penis or vagina may either be signs of infection or an early cancer, and should not be overlooked.

Unusual bleeding can happen in either early or advanced cancer.

Blood in the sputum (phlegm) may be a sign of lung cancer.

Blood in the stool (or a dark or black stool) could be a sign of colon or rectal cancer.

Blood in the urine may be a sign of bladder or kidney cancer.

A bloody discharge from the nipple may be a sign of breast cancer.

Many cancers can be felt through the skin, mostly in the breast, testicle, lymph nodes (glands), and the soft tissues of the body. A lump or thickening may be an early or late sign of cancer.

While they commonly have other causes, indigestion or swallowing problems may be a sign of cancer of the esophagus, stomach, or pharynx (throat).

A cough that does not go away may be a sign of lung cancer.

A cancer may be suspected for a variety of reasons, but the definitive diagnosis of most malignancies must be confirmed by histological examination of the cancerous cells by a pathologist.

TREATMENT

Once diagnosed, cancer is usually treated with a combination of surgery, chemotherapy and radiotherapy.

Radiation therapy may be used to treat almost every type of solid tumor, including cancers of the brain, breast, cervix, larynx, lung, pancreas, prostate, skin, stomach, uterus, or soft tissue sarcomas.

Most forms of chemotherapy target all rapidly dividing cells and are not specific for cancer cells, although some degree of specificity may come from the inability of many cancer cells to repair DNA damage, while normal cells generally can.

Contemporary methods for generating an immune response against tumours include intravesical BCG immunotherapy for superficial bladder cancer, and use of interferons and other cytokines to induce an immune response in renal cell carcinoma and melanoma patients.

Pain medication, such as morphine and oxycodone, and anti-emetics, drugs to suppress nausea and vomiting, are very commonly used in patients with cancer-related symptoms. transmission and disease.

Advances in cancer research have made a vaccine designed to prevent cancer available. The vaccine protects against four HPV types, which together cause 70% of cervical cancers and 90% of genital warts.

The consensus on diet and cancer is that obesity increases the risk of developing cancer. The cancer-fighting components of food are also proving to be more numerous and varied than previously understood, so patients are increasingly being advised to consume fresh, unprocessed fruits and vegetables for maximal health benefits.

Prostate Health Meets Soy Health

By : Dee Overly

One passage into middle age for men is the dreaded prostate exam. No it's not fun but it is necessary. Prostate cancer is men's second most frequent cancer in the United States.

But one must look at the world in order to fully understand prostate cancer and men's health, in general.

Prostate cancer is a disease that is more common in certain populations. If you're an African American male living in the United States, your chances for developing prostate cancer is greater than if you are an Asian man living in Indonesia.

Due to this phenomenon, many studies have found that prostate cancer can be directly linked to diet and food choices. In fact, it is believed that an estimated 75% of all diagnosed prostate cancers could be avoided if better eating habits and dietary changes were followed.

That's a promising note for American males, so let's dive into the particulars and see why soy is so great for prostate health.

Isoflavones are plant compounds found in soy products. Isoflavones act as hormones in the human body and can actually have great effects on several bodily functions.

For example, they can help lower your cholesterol, maintain good blood glucose levels, and even help build healthy bones. But for men, they can also act as inhibitors for prostate cancer.

It is for this reason that many studies have asked why? Why is it that Asian men are more prone to avoiding prostate cancer? Why is it that the American male tends to have larger prostates in their later years their Asian counterparts?

The best found answer to this question has been diet. It is no secret that the Asian population has been eating soy for over one thousand years. Most infants and children in the Asian population will find themselves eating the 80 to 100 mg of soy per day. After a number of years, the isoflavones in their bodies will build and their chances for prostate cancer will be reduced with each bite.

One recently conducted study focused on a group of 41 patients who were diagnosed with prostate cancer. These patients were given 100 mg of an isoflavone supplement twice a day for 6 months.

Results showed a lowering of the prostate-specific antigen (PSA) levels and ultimately a slowing of the prostate cancer growth. PSA is a protein produced by the cells of the prostate gland. The higher the PSA level, the more likely there is cancer present.

Isoflavones are found in all soy foods. One need only drink one 8 ounce glass of soymilk per day to receive 40 mg of isoflavones. Currently there is no recommended dosage of isoflavones to help lower prostate cancer risks.

However, the FDA has recommended that a person needs approximately 25 grams of soy protein per day in order to lower cholesterol levels.

Although more studies are underway to further investigate the relationship between soy isoflavones and prostate health, preliminary studies contain a hopeful future for the male population. When it comes to lowering the risks and avoiding prostate cancer, it seems that diets high in soy have been labeled a promising ally.
