Cancer: Overview

Cancer is the general class of diseases caused by the bodyís own cells reproducing too rapidly. The dividing cells usually create a solid tumor from a mass of body cells, but some types of cancer cause too many cells circulating throughout the body rather than a lump (e.g. leukemia). A tumor needs to be classified as a benign tumor (non-cancerous) versus a malignant tumor (cancerous). A tumor also needs to be distinguished from a variety of other types of lumps (e.g. cysts, abscess, angioma, etc.). Common types of cancer include lung cancer, colon cancer, skin cancer, and many other types of cancer. Diagnosis and treatment of the various types of cancer varies greatly depending on the exact type. General themes of treatment for cancer include chemotherapy (medications), radiotherapy (radiation), surgery (removal of a tumor), and immune therapies.
