Below is a list of some or all of the tests used to diagnose this type of cancer. We have more information on other diagnostic tests for cancer.
An X-ray can show whether the fluid around the organ has thickened.
A CT scan can show the size and location of the tumour and whether it has spread.
A needle can be inserted to retrieve a tissue sample that will be tested for cancer.
Surgery may be required to explore the affected area, to get a tumour sample or to remove the entire tumour.
Types & Stages
Staging describes the extent of a cancer. The TNM classification system is used as the standard around the world. In general a lower number in each category means a better prognosis. The stage of the cancer is used to plan the treatment.
T describes the site and size of the main tumour (primary);
N describes involvement of lymph nodes;
M relates to whether the cancer has spread (presence or absence of distant metastases).
Stage I Mesothelioma involves the right or left pleura and may also have spread to the lung, pericardium, or diaphragm on the same side. Lymph nodes are not involved.
Stage II Mesothelioma has spread from the pleura on one side to nearby lymph nodes next to the lung on the same side. It may also have spread into the lung, pericardium, or diaphragm on the same side.
Stage III Mesothelioma is now in the chest wall, muscle, ribs, heart esophagus, or other organs in the chest on the same dies with or without spread to lymph nodes on the same side as the primary tumour.
Stage IV Mesothelioma has spread into the lymph nodes in the chest on the side opposite the primary tumour, to the pleura or lung on the opposite side, or directly into organs in the abdominal cavity or neck. Distant spreading or metastases is also included in this stage.
