Description Sarcoma is a cancer of the connective tissues that hold the body together including the muscles, tendons, blood vessels, fat, nerves, bones and cartilage. Sarcomas develop in the bone or muscle or tissue or blood vessels. Nearly half of soft tissue sarcomas start in the arms and legs. Sarcomas can metastasize with great rapidity.
Symptoms of bone cancer (osteosarcoma) begin in the bone cells and may include but are not restricted to, bone pain, tenderness of the area, brittle bones resulting in a fracture, problems with mobility (stiff joints), bruising, loss of muscle tone, a lump or swelling near a joint. Most often it is found in the ends of the long bones of the body, such as the arms and legs.
Chordoma is a rarer low-grade cancer mostly found at the base of the spine, followed by the base of the skull. Sites that are impacted include the vertebral column, ribs, lower limbs, head, upper limbs, pelvic bones.
Adamantinomas occur mostly in the lower leg bones. These are often wrongly diagnosed as growing pains in children, pulled muscle or nerve damage in young adults or arthitris in elder patients. Among common symptoms bone pain can be worse at night and can intensify in time and morph into stiffness or a pronounced limp.
Pelvic bones and upper limbs cancers are known as Ewing sarcoma or chondrosarcoma (and osteosarcoma). These cases are more common among adults.
