A sarcoma is a tumor of your connective tissue including muscle, fat, bone, blood vessels, cartilage and other connective tissues.
The most common cancers are carcinomas and include breast, prostate, lung, and colon cancer. Cancers of the blood and immune system are are leukemias and lymphomas. These are different cancers from sarcomas.
It is unclear how most sarcomas arise. Some patients can have a familial syndrome that can lead to a sarcoma, but these are rare cases.
Sarcomas are cared for by teams of doctors. At UCLA, we have a group of surgeons, pathologists, medical oncologists, radiation oncologists and radiologists who take care of sarcoma patients.
