Moreover the symptoms of the disease don’t typically manifest for several years after contraction. This makes this disease even harder to be diagnosed at a proper time and often it becomes too late for any doctor to do something really constructive. So the first thing that you should do is to tell your doctor in advance if you’re regularly exposed to asbestos. Otherwise after seeing the symptoms he could put those down to some other disease before testing for mesothelioma.

The diagnosing of mesothelioma begins with a CT or MRI scan to detect its presence and if the results show any positive sign then a biopsy is conducted. The initial scans help the doctor to view the affected area so he will prepare a suitable plan to counter it. The doctor may do a minor operation to get a tissue sample of your lungs or other body part and run a diagnostic test on that. This is known as open pleural diagnostic test. While there are several other techniques to find the evidences of mesotheliom, experts consider pleural diagnostic test to be the most convincing way of diagnosis mesothelioma.

There are more than some ways in which the doctor will perform a tissue diagnostic test in order to check for mesothelioma. A thoracoscopy or laparoscopy involves making a small cut then keeping an eye over the infected area with the help of a tiny camera. Your doctor may do a needle biopsy in which a hollow needle is inserted into the chest cavity in order to collect a tissue sample which is then examined by the pathologist.

However, with open diagnostic test the doctor will collect a bigger tissue sample which makes diagnosing easier and even more precise which is why most physicians adhere to this technique. Once the tissue samples have been collected, a detailed examination of the cells is performed to check for malignant cells in the tissue.
