Cancer surgery is used to treat cancer, in which abnormal cells multiply and spread throughout the body, forming tumors. These cancers are usually named for the place in the body where they originate—e.g., prostate cancer or liver cancer.
There are five main categories of cancer:
- Carcinoma: Cancer that begins in the skin or tissues lining or covering internal organs.
- Sarcoma: Cancer that begins in bone, cartilage, fat, muscle, blood vessels, and other connective or supportive tissue.
- Leukemia: Cancer that begins in blood-forming tissue such as bone marrow.
- Lymphoma and myeloma: Cancers that form in the cells of the immune system.
- Central nervous system cancers: Cancers that begin in the tissues of the brain and spinal cord.
