3 comments | Sarcoma is a type of cancer that develops from tissues within the bone or muscle and is often a source of pain. The main types of sarcoma include bone and tissue sarcomas. Because it’s a rare condition, the facts about sarcoma are often misunderstood. How much do you know about sarcoma? If you're experiencing unusual, or unexplained pain, talk to your provider as soon as you can. | EmblemHealth | Facebook
