Ewing’s sarcoma is a cancerous tumor which normally begins in or near a bone and sometimes arises in soft tissue. The tumors can form on any bone, but usually affect long bone. It commonly develops in the bones of the upper arm and leg. Ewing’s sarcoma is a primary bone cancer because it grows from within the bone. These tumors can be cancerous and may spread to other parts of the body, including the lungs and bone marrow.
There are four kinds of Ewing’s tumors. When combined, they are called the Ewing family of tumors (EFT). Three types of Ewing’s tumors occur in the bone including:
- Classic Ewing’s sarcoma of the bone
- Primitive neuroectodermal tumors (PNET)
- Askin tumors (PNET of the chest)
One that occurs in the tissue is known as Ewing sarcoma or Ewing sarcoma of the soft tissue
Causes of Ewing Family of Tumors
Experts have limited knowledge on what causes Ewing family of tumors
. No risk factors have been identified. There are no known ways to prevent Ewing’s sarcoma. Researchers have found one strange thing with Ewing’s sarcoma patients which is that they have non-inherited genetic mutations in chromosomes 11 and 22.
