Malignant Peritoneal Mesothelioma
By Ryan T Murphy

Background:

"Malignant Peritoneal Mesothelioma is a rare form of cancer in which (cancerous) cells are found in the mesothelium, a protective sac that covers most of the body's internal organs." The disease then proceeds to affect the abdomen wall or in this case, the peritoneum. It then goes on to infect a serious of membranes in the region as well as the membranes that enclose several other major organs. Mesothelioma is most oftenly found in people who have in some way inhaled asbestos particles or other airborn particles at their job or place of residence. Although, there is no connection between mesothelioma and smoking, which is a major factor in lung cancer. While smoking has not been proven to cause mesothelioma, it has been found to increase the risk of other asbestos-induce cancer. Of the 2.6 million annually diagnosed cases of mesolthelioma, 15% to 20% are peritoneal mesothelioma.

Asbestos

"Asbestos is a naturally occurring silicate mineral with long thin fibrous crystals." This naturally occurring substance has been used in fire retardant coatings, bricks, pipes, drywall, and roofing. Its importance became known during the Industrial Revolution and is now being utilized in various ways. Although this mineral has numerous practical appliances, it does have very hazardous effects on the body. If inhaled, asbestos particles are known to cause very serious and potentially fatal diseases such as lung cancer, malignant mesothelioma, and asbestosis. Various other minor effects of asbestos exposure include asbestos warts, pleural plaques, and diffuse pleural thickening. While these conditions can all be a results of asbestos exposure, malignant "peritoneal" mesothelioma is the most deadly. Basically, mesothelioma is a lethal cancer that "attacks the membranes around the lungs, the heart, and the abdominal cavity." Of the various forms of this cancer, mesothelioma of the lung is most common. Mesothelioma of the lung, much like that of lung cancer, is a very deadly and underdiagnosed disease because of the very subtle symptoms. Fortunately for those who have inhaled asbestos fibers, it takes years for the fibers to infect the membranes and then cause fluid accumulation and even tumor development. Asbestos particles are extremely harmful for they can result in the development of lethal diseases.
