There are four main types of mesothelioma, based on the location the tumour initially develops. These are testicular, pericardial (heart), pleural (lungs), and peritoneal (abdomen). Furthermore, mesothelioma may be grouped based on cell type-biphasic, sarcomatoid, and epithelioid- according to malignancy. This article is going to discuss in detail different types of mesothelioma by location. Here are some of the symptoms to look for if you have been exposed to mesothelioma.
Types of Mesothelioma by Location
The thin tissue lining from where mesothelioma develops, called mesothelium, is found in some parts of the body, like the chest area surrounding the abdominal cavity and the lungs. The most common method of classifying mesothelioma is to establish where in the mesothelial layer the disease starts from.
Pleural Mesothelioma (Lungs)
This develops in the lungs linings (called the pleura). Pleural mesothelioma, as the most common form of this disease, accounts to about 80 percent of new cases
Pleural mesothelioma is not easy to diagnose. In its early stage, symptoms appear to be mild, and in later stages (in stage 3 or 4), symptoms may significantly worsen. Unfortunately, because it’s sometimes diagnosed at some later stage, normally mesothelioma has a poor prognosis-majority of patients will live less than 17 months from that time that their first symptoms appear.
Peritoneal Mesothelioma (Abdomen)
This type originates in the abdomen lining. Often, it spreads to the abdominal organs, which include bowel, spleen, and liver. The most common symptom is acute abdominal pain, followed by discomfort originating from fluid buildup (abdominal effusion).
Even though its prognosis is poor, in recent years it has improved somehow, mostly because of new treatments like hyperthermic intraperitoneal chemotherapy (HIPEC). Results vary from one patient to the other, but, survivorship depends normally on the patient’s condition as well as specific diagnostic factors.
Pericardial Mesothelioma (Heart)
This type of mesothelioma, originating in the heart cavity lining (the pericardium), is rare-accounting for less than 1 percent of all cases of mesothelioma. As this rare type of cancer develops, the heart becomes not able to deliver oxygen to the body. This leads to, at an increasingly rapid rate, further decline in health.
Its most common symptoms similar to those of heart attack, like shortness in breath and pain in the chest. In several instances, it may go undiagnosed till autopsy is performed.
This kind of mesothelioma is very rare form of the disease. It has less than 100 cases having been diagnosed worldwide. Since there are so few incidents of this kind of mesothelioma, there’s little understood about its development, and there are no available standard course of treatment.
