Sarcomas are a type of cancer that develops from the soft tissues (fleshy parts) of the body, as well as from bone and fatty tissue. This type of cancer is different from carcinomas. Carcinomas develop more frequently in the body's organs, especially those organs that contain glands. Examples of carcinomas include lung cancer, colon cancer, pancreatic cancer, breast cancer, prostate cancer.
Rhabdomyosarcoma is a cancer that forms in the skeletal muscles. Skeletal muscles attach to bones. They help the body move. Most rhabdomyosarcomas occur in children and teenagers.
