Mesothelioma diagnosis is not an easy task, as the symptoms map to other lesser ailments, as mentioned above. The first step to diagnosing mesothelioma is a review of the patient’s medical history.

It is important to know if the patient has had any illnesses whose symptoms mesothelioma too displays. At this time, it is also important to know if the patient has had prior exposure to asbestos. If the patient hasn’t had any illnesses displaying the symptoms related to mesothelioma, and has had exposure to asbestos, then there can be suspicion of mesothelioma.

It is important to do a detailed physical examination of the patient, including x-rays, CT scans, and MRIs. The focus would usually be on the abdominal and chest regions. If there is anything suspicious at the end of these examinations, it is advisable to do a biopsy.

A biopsy is usually done by a specialist, either an oncologist or a surgeon. Biopsy involves taking a tissue sample from the patient and subjecting it to specific tests to determine the presence or absence of mesothelioma. Biopsy in the case of mesothelioma can be:

• Thoracoscopy (done by taking tissue samples from inside the chest region, using a thoracoscope)
• Peritoneoscopy (done by taking tissue samples from the abdominal region, using a peritoneoscope)

Once the diagnosis is made, it is vital to learn the stage at which mesothelioma has been detected. Depending on whether the cancer is still at the original site or whether it has spread to other parts of the body, the mesothelioma can be called:

• Localized (still at the original site)
• Advanced (spread to other parts of the body)

Mesothelioma treatments vary depending on the type of mesothelioma, as also the stage at which it has been detected. The three most commonly used treatment forms against mesothelioma are:

• Surgery – Surgically removing the cancerous body part. For example, malignant pleural mesothelioma treatment could involve removal of the affected lung by performing a pneumonectomy.
• Radiation therapy – Exposing the affected part to high-energy rays to kill the malignant cells
• Chemotherapy – Using chemicals/drugs to destroy the malignant cells, either by injecting them into the patient, or intravenously, or by direct placement in the chest or abdomen (intracavitary chemotherapy).

Besides these three options, research is underway to find newer and more effective treatment options. Clinical trials have played a major role in developing newer treatment options.
