Mesothelioma Cancer
Its transcendently common site is the pleura (outer lining of the lungs and chest cavity), but it may also occur in the peritoneum (the lining of the abdominal cavity) or the pericardium (a sac that surrounds the heart).
Unlike lung cancer, there is no association between mesothelioma and smoking Malignancies involving mesothelial cells in these spread cavities are known as malignant mesothelioma, which may be localized or diffuse. Mesothelioma is the word used to describe a cancerous tumor that involves the mesothelial cells of an organ, often the lungs, heart, or abdominal organs.
In this disease, malignant cells develop in the mesothelium, a protective lining that covers transcendently of the spread's internal organs. Greatest malignant mesotheliomas set up complex karyotypes, with extensive aneuploidy and rearrangement of tons chromosomes.
Symptoms of mesothelioma may not appear until 20 to 50 years after exposure to asbestos. Diagnosing mesothelioma is often difficult, because the symptoms are similar to those of a number of other conditions. A history of 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.
If the cancer has length beyond the mesothelium to other parts of the size, symptoms may include pain, trouble swallowing, or swelling of the neck or engage.
Tissue is removed, placed under the microscope, and a pathologist makes a definitive diagnosis, and issues a pathology report. Mesothelioma is diagnosed by pathological examination from a biopsy.
Symptoms of peritoneal mesothelioma include weight loss and cachexia, abdominal swelling and suffering due to ascites (a buildup of fluid in the abdominal cavity). Malignant mesothelioma has also been linked to curing radiation using thorium dioxide and zeolite, a silicate in the soil.
Malignant mesothelioma is often just called simply Mesothelioma and is a form of lung cancer that is quite rare.
After two straight years of historic decline, the number of cancer deaths in the United States increased in 2005, a new study shows.
