A sarcoma is a rare kind of cancer. Sarcomas are different from the much more common carcinomas because they happen in a different kind of tissue. Sarcomas grow in connective tissue -- cells that connect or support other kinds of tissue in your body. These tumors are most common in the bones, muscles, tendons, cartilage, nerves, fat, and blood vessels of your arms and legs, but they can happen anywhere. Although there are more than 50 types of sarcoma, they can be grouped into two main kinds: soft tissue sarcoma and bone sarcoma, or osteosarcoma.
Osteosarcoma is a type of bone cancer that occurs when osteoblasts mutate into cancerous cells. These cancerous cells continue to divide at an increasing rate, forming a tumor. Tumors usually develop in the growth plate, or metaphysis, the wide section of the bone that grows during childhood. Osteosarcoma can develop in any bone of the body. However, it is more likely to develop in the femur, tibia, and humerus. The most common symptoms of osteosarcoma are pain and swelling at the tumor site. Osteosarcoma usually affects patients between the ages of 10 and 20, during the adolescent growth spurt. Males and African-Americans are more likely to develop osteosarcoma.
