Mesothelioma: Benign or Malignant
By Rick Ferring
Mesothelioma, a rare form of lung cancer caused by exposure to asbestos, is typically broken into two types ?benign and malignant. The asbestos, when disturbed, releases particles into the air, which are then swallowed or inhaled. Once inside the body, these foreign bodies become embedded in the soft tissue lining in the body. Where these particles become large, helps to determine the type of that has or could develop. But with any type of tumors, its important to first understand if it is benign or malignant.
Benign is a noncancerous tumor of the pleura (the lining of the lung and chest cavity). This nonmalignant is usually a tumor concentrated in one spot and affects men more than women. The tumor can grow large enough that it compresses the lung, causing shortness of breath.
Malignant is a cancerous tumor of the pleura or peritoneum (lining of the abdomen) or pericardium (sac surrounding the heart) and is almost always caused by sustained exposure to asbestos. This type of is a widespreading tumor that also affects men more frequently than women. Its the prolonged exposure to asbestos that appears to be the predominant risk factor.
Malignant is then divided into 3 main categories and further divided once again into 3 subcategories. The three main categories are pleural mesothelioma, peritoneal and pericardial
mesothelioma.
Pleural type grows in the tissues covering the lungs. Pleural spreads within the chest city, sometimes it involves the lung. Approximately 70 - 80% of cases are pleural mesothelioma. Peritoneal grows in the tissues lining the inside of the abdomen. It can involve the abdominal cavity, liver, spleen or the bowel. Pain is the most common complaint and because of the fluid accumulation, the abdomen often appears swollen. This type of is only found in approximately 10 ?20% of the diagnosed cases. The third main type is pericardial mesothelioma, which grows within the heart and the sac enclosing the heart. This is the rarest of the three and only accounts for 5 ?0% of the cases.
Within the three main categories, there are three main sub types that are sorted by how the cells look under a microscope. The three sub types are epithelioid mesothelioma, sarcomatoid and biphasic mesothelioma.
About 50 to 70% of cases are of the epithelioid type. About 7 ?20% of cases are of the sarcomatoid type. And about 20 ?35 % of cases are of the biphasic type.
In order to correctly diagnose and start treatment, physicians need to order tests done to confirm just what type of a person may have.
