| | Mesothelioma |
 | | Mesothelioma is a rare form of cancer that affects the membrane that covers and protects various internal organs of the body (mesothelium). |
 | | The term "cancer" refers to a group of diseases characterized by abnormal, uncontrolled cellular growth (e.g., mesothelial cells) that invades surrounding tissues and may spread (metastasize) to distant bodily tissues or organs via the bloodstream, the lymphatic system, or other means. |
 | | Different forms of cancer, including mesothelioma, may be classified based upon the cell type involved, the specific nature of the malignancy, the tissues or organs affected, and the disease's clinical course. |
