Osteosarcoma affects twice as many guys as girls, and tends to show up in people who are taller than average. The same is true if a teen has received bone radiation treatments for other cancers. The most common symptoms of osteosarcoma are pain and swelling in an arm or leg that is sometimes accompanied by a lump. Some people have more pain at night or when they exercise . Osteosarcoma is most often found in the bones around the knee.
Treatment depends upon the stage or level of osteosarcoma.
Low-grade osteosarcoma is usually treated with surgery only. Intermediate-grade osteosarcoma usually requires surgery or a combination of surgery and chemotherapy. High-grade osteosarcoma generally requires surgery as well as chemotherapy. For specific medical advice, diagnoses, and treatment, consult your doctor.
