What Is Sarcoma?

Cancer conditions are named differently depending on the place of occurrence in the body. Cancer that can occur on the bone and muscles are known as sarcoma. If the sarcoma occurs on the soft tissues like nerves, blood vessels, muscles, and fat, then it is mentioned as soft tissue sarcoma.

What Is Ewing Sarcoma?

If there is any miscommunication due to the mutations, it might result in genetic problems and abnormal cell growth. These abnormal cells begin to spread and cause the destruction of healthy cells. In Ewing sarcoma, there is an alteration in the gene EWSR1. People who are having severe exposure to radiation are also known to be affected by Ewing sarcoma.
