Cells capable of forming malignant tumors exhibit many properties which distinguish them from the cells of healthy tissue. They are resistant to apoptosis ("programmed" cell death). They have an uncontrolled ability to divide (or, they are immortal), and they often divide at an increased rate. These cells are self-sufficient with respect to growth factors. They are insensitive to antigrowth factors, and contact inhibition is suppressed.< ...

Cell division (proliferation) is a physiological process that occurs in almost all tissues and under many circumstances. Normally homeostasis, the balance between proliferation and programmed cell death, usually in the form of apoptosis, is maintained by tightly regulating both processes to ensure the integrity of organs and tissues. Mutations in DNA that lead to cancer disrupt these orderly processes by disru ...

See also asbestos and the law In the United States, the average mesothelioma-related settlement was $1 million; for cases that go to trial awards averaged $6 million, according to a study by the RAND Corporation. Only a small fraction of the thousands of asbestos-related lawsuits in the United States every year are related to mesothelioma. In 2004, a bill in the United States Senate aimed a asbestos litigation reform failed to reach a floor vote. In January of 2005, Senate Judiciary Committee Chairman Arlen Specter announced he would again tr ...

An article published by Wagner et al in 1960 first established mesothelioma as a disease arising from exposure to crocidolite asbestos[6]. The article referred to over 30 case studies of people who had suffered from mesothelioma in South Africa. Some exposures were transient and some were mine workers. In 1962 Dr McNulty reported the first diagnosed case of malignant mesothelioma in an Australian asbestos worker^{See also:}

Treatment of MM using conventional therapies has not proved successful and patients have a median survival time of 6 - 12 months after presentation. The clinical behaviour of the malignancy is affected by several factors including the continuous mesothelial surface of the pleural cavity which favours local metastasis via exfoliated cells, invasion to underlying tissue and other organs within the pleural cavity, and the extremely long latency period between asbestos exposure and development of the disease.

Symptoms of mesothelioma may not appear until 30 to 50 years after exposure to asbestos. Shortness of breath and pain in the chest due to an accumulation of fluid in the pleural space are often symptoms of pleural mesothelioma. Symptoms of peritoneal mesothelioma include weight loss and cachexia, abdominal swelling and pain due to ascites (a buildup of fluid in the abdominal cavity). Other symptoms of peritoneal mesothelioma may include bowel obstruction, blood clotting abnormalities, anemia, and fever. If the cancer has spread beyond the mesothelium to other parts of the body, symptoms may include pain, t ...

Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions. Diagnosis begins with a review of the patient's medical history. A history of occupational exposure to asbestos may increase clinical suspicion for mesothelioma. A physical examination is performed, followed by chest X-ray and often lung function tests. The X-ray may reveal pleural thickening commonly seen after asbestos exposure and increases suspicion of mesothelioma. A CT (or CAT) scan or an MRI is usually performed. If a ...

Once the diagnosis is confirmed, the doctor may need to assess the stage to help plan treatment. Mesothelioma is described as localized if the cancer is found only on the membrane surface where it originated. It is classified as advanced if it has spread beyond the original membrane surface to other parts of the body, such as the lymph nodes, lungs, chest wall, or abdominal organs. ...

Mesothelioma - Incidence. Although reported incidence rates have increased in the past 20 years, mesothelioma is still a relatively rare cancer. The incidence is approximately one per 1,000,000. For comparison, populations with high levels of smoking can have a lung cancer incidence of over 1,000 per 1,000,000. Incidence of malignant mesothelioma currently ranges from about 7 to 40 per 1,000,000 in industrialized Western nations, depending on the amount of asbestos exposure of the populations during the past seve ...
