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
