Sarcoma Awareness Month strives to raise awareness about what is considered to be the “forgotten cancer.” Sarcoma is an uncommon group of cancers which arise in the bones, and connective tissue such as fat and muscle. In most cases, it’s not clear what causes sarcoma. Family history and exposure to chemicals or radiation may increase risk. There are no standard screening tests for sarcoma. You should examine your body for any unusual or new lumps or bumps that are growing. It is very important to make an appointment with your doctor to be examined.
