Stages of malignant mesothelioma - explanation

Once malignant mesothelioma is found, more tests will be done to find out if cancer cells have spread to other parts of the body. This is called staging. A doctor needs to know the stage of the cancer to plan treatment. The following stages are used for malignant mesothelioma.

• Localized malignant mesothelioma
  

Stage I

The cancer is found in the lining of the chest cavity near the lung and heart or in the diaphragm or the lung.

• Advanced malignant mesothelioma
  

Stage II

The cancer has spread beyond the lining of the chest to lymph nodes in the chest.

Stage III

Cancer has spread into the chest wall, center of the chest, heart, through the diaphragm, or abdominal lining, and in some cases into nearby lymph nodes.

Stage IV

Cancer has spread to distant organs or tissues.

Recurrent malignant mesothelioma

Recurrent disease means that the cancer has come back (recurred) after it has been treated. It may come back in the lining of the chest or abdomen or in another part of the body.
