Sarcomas

Sarcomas are a rare group of cancers that occur more commonly in children and rarely in adults. It is a cancer of the connective tissue or cells whose primary function is to hold or connect the body together. These sarcomas can be broken down into soft tissue sarcomas or tissues that connect, surround or support tissues or organs of the body including the nerves, fat, muscles tendons and blood tissues, and hard tissue sarcomas that affect the bone and cartilage. Primary bone cancer is rare with the most common type of bone cancer being osteosarcoma, which develops in new tissue in growing bones. Others include chondrosarcoma of cartilage tissue and Ewing's sarcoma in immature nerve tissue in bone marrow. Bone sarcomas occur more frequently in the extremities such as the arms and legs.
