In general, the higher the stage of cancer the more difficult it is to treat. There are hundreds of different types of cancer. They are identified by the type of body tissue involved or by the body part involved. Carcinoma is a malignant tumor found in the outermost covering or lining of body surfaces or organs. These tumors are found on the skin, in the mouth and throat, stomach and bowel, or in organs like the breast, prostate, colon, lung or bladder.
Sarcoma is a malignant tumor found in connective tissues such as bone, muscle and cartilage.
Leukemia is a malignant disease found in bone marrow and other blood forming organs. Glioma is cancer in the brain, spinal cord or nerves. Lymphoma is a malignant tumor of the lymph glands or other lymphatic tissues.
