The Cause Of Cancer
Cancer is the disease of the cells. It is an abnormal growth of cells, which tend to reproduce in an uncontrolled way and, in some cases, spread or metastasize. A cancerous growth or tumor is also known as a malignant growth or tumor. A growth or tumor, which is non-malignant is called benign. Such tumors are not cancer.
Cancer is not a single disease. It is a group of more than hundred different and distinctive diseases. It is not contagious. Cancer can involve any tissue of the body and have many different forms in each body area. Most cancers are named for the type of cell or organ in which they start. If a cancer spreads (metastasizes), the new tumor bears the same name as the original(primary) tumor.
Cancer is the Latin word for crab. The ancients used the word to mean a malignancy, doubtless because of the crab-like tenacity a malignant tumor sometimes seems to show in grasping the tissues it invades. Cancer may also be called malignancy, a malignant tumor, or a neoplasm (literally, a new growth).
In medicine, common term for neoplasms, or tumors, that are malignant is known as Cancer. Like benign tumors, malignant tumors do not respond to body mechanisms that limit cell growth. Unlike benign tumors, malignant tumors consist of undifferentiated, or unspecialized, cells that show an atypical cell structure and do not function like the normal cells from the organ from which they derive. Cancer cells, unlike normal cells, lack contact inhibition; cancer cells growing in laboratory tissue culture do not stop growing when they touch each other on a glass or other solid surface but grow in masses several layers deep.
Cancer results from mutations of certain genes that allow the cells to begin their uncontrolled growth. These mutations are either inherited or acquired. Acquired mutations are caused by repeated insults from triggers (e.g., cigarette smoke or ultraviolet rays) referred to as carcinogens. There is usually a latency period of years or decades between exposure to a carcinogen and the appearance of cancer. This, combined with the individual nature of susceptibility to cancer, makes it very difficult to establish a cause for many cancers.
The most significant avoidable carcinogens are the chemical components of tobacco smoke. Dietary components, like excessive consumption of alcohol or of foods high in fat and low in fiber rather than fruits and vegetables that contain antioxidants and necessary micronutrients, have also been linked with various cancers. Some cancers may be triggered by hormone imbalances. For example, some daughters of mothers who had been given DES (diethylstilbestrol) during pregnancy to prevent miscarriage developed vaginal adenocarcinomas as young women. Aflatoxins are natural mold byproducts that can cause cancer of the liver.
Certain carcinogens present occupational hazards. For example, in the asbestos industry, workers have a high probability of developing lung and colon cancer or a particularly virulent cancer of the mesothelium (the lining of the chest and abdomen). Benzene and vinyl chloride are other known industrial carcinogens.
Risk to humans from carcinogens depends upon the dose and a person's biologic susceptibility. Factors influencing a person's biological susceptibility to cancer include age, sex, immune status, nutritional status, genetics, and ethnicity.

Mesothelioma: Treatments for Mesothelioma Cancer
Mesothelioma cancer is currently treated through three treatments, depending on the cancer location, the disease stage, and the patient's general health and age. These treatments are surgery, chemotherapy and radiation therapy, which sometimes are combined to fight the disease in so far as possible.
In a surgery, one of the most common treatments for mesothelioma, the doctor removes part of the lining of the abdomen or the chest and some tissue around it. In a pneumonectomy, the doctor may also remove one lung when the patient has pleural mesothelioma or cancer of the pleura. In other surgical procedure, the doctor may also remove part of the diaphragm, the muscle below the lungs that helps with breathing.
Through these procedures, the medical specialist shall try to excise tumourous tissue arising from this cancer disease. As these operations will reduce the patient's respiratory capacity, the surgeon will evaluate the patient's ability to function after a lung tissue removal, before performing a pneumonectomy.
Another method to fight Mesothelioma is chemotherapy or the use of anticancer drugs to kill cancer cells throughout the body. These drugs are given to the patient by an intravenous procedure, an injection into a vein. Currently, experts are studying the effectiveness of intracavitary chemotherapy or the possibility of giving chemotherapy straight to the chest or abdomen.
Radiotherapy or radiation therapy is the use of high-energy rays to destroy malignant cells and shrink tumors. It is important to know that this medical procedure attacks the cancer cells only in the treated area. There are two ways of giving this therapy. One, external radiation, in which the radiation comes from a machine, and other, internal radiation, where the cancer cells are found after putting materials that produce radiation into the affected area. Doctor's way to relieve patient's pain is to use a needle or a thin tube to drain fluid that has built up in the abdominal or chest cavities through a procedure called thoracentesis, when it is from the chest, and paracentesis, when the removal is from the abdomen. The specialists may also give the drugs through a tube in the chest to prevent the accumulation of more liquid.

Mesothelioma - The Cause Of Cancer
What Is Mesothelioma?
Mesothelioma the medical name for cancer of the pleura (the lining of the lung and chest cavity) or cancer of the peritoneum (the lining of the abdomen). It is usually caused by prolonged or persistent exposure to asbestos.
Symptoms of mesothelioma may not appear until between twenty and fifty years after exposure, which explains why so many new cases of this form of cancer are coming to light now, even though the dangers of asbestos were realized long ago and measures taken to reduce the risk of the disease.
As with many forms of cancer, the mesothelioma tumor can spread rapidly, often infecting the opposite pleura, and continuing on to other internal organs. Symptoms include a shortness of breath, chest pains, coughing, and loss of weight.
Testing can be carried out initially by X-Ray, with a Thoric CT and open lung biopsy being used to confirm the findings of the early tests. If it is diagnosed early enough, the tumor can be surgically removed, and with follow-up chemotherapy and radiation treatment, full recovery is often possible.
However, in more advanced cases, cure is usually not possible. In such cases, chemotherapy and radiation treatment can be used alongside other pain relief treatments, to ease the symptoms. Where cure is not possible, the average survival time is between four and eighteen months, depending on the stage of the tumor and the general health of the patient.

"Mesothelioma" is the term used to describe a cancerous tumor that involves the mesothelial cells of an organ. Mesothelial cells are cells that form a protective lining over the lungs, heart and abdominal organs. The most common type of mesothelioma is pleural mesothelioma. The pleura is a thin membrane found between the lungs and the chest cavity. It provides a lubricated surface so that the lungs do not rub and chafe against the chest walls. What causes it?
Virtually all cases of mesothelioma are related to inhaling of asbestos fibers. There are about 3,000 cases per year (mostly men over the age of 40) and there will be about 300,000 cases before 2030. Mesothelioma usually spreads rapidly through the mesothelial cells to the heart and abdominal organs. The life span is typically 24 months after diagnosis, but it depends on what stage the cancer is detected, the health of the patient and other factors. Although asbestos exposure causes mesothelioma, it has a latency period after exposure that could last 15 to 50 years. This means that someone who worked in a factory with asbestos 40 years ago could be developing mesothelioma now. Anyone who knows they were exposed to loose asbestos fibers should be tested regularly for mesothelioma.
Diagnosis - The onset of mesothelioma is usually very slow. The first symptom is a constant pain in the chest. This pain is later accompanies by difficulty breathing due to an accumulation of fluid in the chest. Other symptoms include coughing, fever and weight loss. Mesothelioma can be diagnosed by your doctor with a chest CT-scan.
Prognosis (the outcome) Mesothelioma advances in 4 stages:
Stage I - the tumor is limited to the area of the lining of the lung and usually limited to only one side of the chest. Stage II - the tumor extends to other organs within the chest cavity, such as the heart or lymph nodes in the chest. Stage III - the tumor expands to the other side of the chest or it spreads into the abdominal organs. The lymph nodes outside the chest are affected. Stage IV -the cancer spreads to different parts of the body far outside the chest area (liver, brain, bone, etc...).
Mesothelioma is an extremely deadly disease. The average survival time is about one year from date of diagnosis. About 20% of patients who find their cancer early and treat it aggressively will reach the five-year mark. for more information and articles about mesothelioma go to http://www.mesothelioma-health.net

Cancer Diet - Minerals
A cancer diet needs a good balance of minerals because minerals are needed by all cells for proper function. Patients are often found to be mineral deficient, so this is an area of the diet that needs particular attention.
There are two classes of minerals. Macrominerals, such as the well known calcium, magnesium, sodium, potassium and phosphorus, and microminerals, such as boron, chromium, copper, iron, iodine, germanium, sulfur, silicon, vanadium, zinc, manganese and molybdenum.
The good news is we will get most of the minerals we need, provided we are eating a diet based on a wide variety of fruits and veggies, with the addition of nuts, seeds and grains.
Where we can get in to trouble is that minerals are washed out of soils with constant rain, and modern fertilizers don't usually contain the wide variety of minerals we need. Organic gardeners usually use rock minerals on their soils and this results in organic produce have a much higher and broader range of minerals.
Germanium is one micromineral that cancer patients are often low on. It is essential for immune function and is critical to tissue oxygenation. Cancer grows rapidly where there is low oxygenation of cells. Germanium is found in broccoli, celery, garlic, onions, rhubarb, sauerkraut and tomato juice as well as aloevera and ginseng.
Iodine deficiency has been linked to breast cancer in more than one study. Seasalt contains iodine and a variety of minerals rather than the isolated highly processed iodine additive in table salt. Asparagus, garlic, lima beans, soybeans, sesame seeds all contain natural iodine along with the nutrients needed for good absorption.
Large amounts of brassicas eg brussels sprouts, cabbage and cauliflower, along with peaches, pears and spinach can block absorption of iodine, so ensure there is a balance of iodine rich foods in your diet.
Selenium has been linked to cancer. Selenium and Vitamin E work together to attack free radicals. Selenium is critical for pancreatic function, and pancreatic enzymes are critical to the bodies ability to fight tumour activity. This mineral is generally found in meat and grains, however countries such as New Zealand and much of America is known to have selenium deficient soils.
As there have been several studies showing that good selenium levels have significantly reduced the risk of cancer, this is one mineral you want to have enough of.
Food sources that should be included frequently in a cancer diet are: brazil nuts, broccoli, brown rice, brewers yeast, chicken, kelp, onions, salmon, seafood, tuna, wheatgerm and whole grains. Garlic, chamomile, ginseng and parsley are all easy to use concentrated forms that can be added to the diet daily.
A couple of warnings:
Be very careful about self-dosing with minerals as several of them will block absorption of others if the dose is too high.
Again, eating a variety of foods, with particular notice taken of those that have high mineral levels is the safest way to go. If you wish to explore mineral supplementation further, talk to your naturopath or nutritionist. But whatever you do, don't ignore the importance of these vital elements to your well being.
