Mesothelioma - Diagnosing this Uncommon Form of Cancer

Mesothelioma is a very rare form of cancer that no more than has around 3000 new cases in America every year. Causes point to asbestos exposure in the past and the cancer can take anywhere from 20 to 40 years to show up.

Once it does, it is in most cases progressed, and the prognosis can be disappointing. Your doctor will probably do a medical history and perform an exam to look for signs of mesothelioma, for instance pleural effusion, ascites or pericardial efflusion. Because it is so uncommon, general screening is by and large not performed. Mesothelioma treatment is regularly carried out for those who are exhibiting symptoms or those that are at risk.

Physicians ordinarily only suspect mesothelioma when all else has been ruled out in combination with symptoms and asbestos related history. If a doctor knows a patient has been exposed to asbestos in a work environment the doctor might test for mesothelioma sooner than if there was no known asbestos contact or other major risk factors.

They are chest x-rays to look for abnormalities that can be signs of mesothelioma such as the thickening of the pleura, calcium deposits on the pleura, or pleural efflusion. CT scan of chest or abdomen are used to get an image of the affected area for possible clues to whether or not cancer is there. To detect tumors and determine its size, magnetic resonance imaging (MRI) is frequently used.

Blood tests are also valuable in detecting mesothelioma. High levels of osteopontin and certain soluble peptides tend to be found in patients who have mesothelioma.

Fluid analysis tests can also be used to help the doctor detect mesothelioma. A long needle is inserted into numbed skin over the chest, abdomen or heart, in procedures respectively called thoracentesis, paracentesis and pericardiocentesis. Pleural, thoracic or abdominal fluid is removed and analyzed. This test does not rule out cancer, but if cancer is present, it can help make a distinction the presence of mesothelioma in opposition to other forms of cancer.
