Ewing Sarcoma

Ewing sarcoma is a group of rare cancerous tumors that typically affect teenagers but can also affect younger kids and young adults. Ewing sarcoma, also known as Ewing’s sarcoma and Ewing tumor, usually affects people’s bones, but can also develop in nearby soft tissues. Thanks to ongoing research and newer treatments, more people with Ewing sarcoma are living longer cancer-free.

Types of Ewing sarcoma

There are three types of Ewing sarcoma:

• Ewing’s sarcoma of bone is the most common type of this condition.
• Extraosseous Ewing tumor (EOE) are tumors in soft tissues like muscles, tendons and ligaments that surround people’s bones.
• Peripheral primitive neuroectodermal tumor (PNET) also starts in bone or soft tissue but has a slightly different genetic makeup than Ewing sarcoma and EOE.

Is Ewing sarcoma common?

No, it’s not common. Each year in the U.S., between 200 and 250 people are diagnosed with Ewing sarcoma. People with Ewing sarcoma may have tumors in their arms and legs, pelvis or spine. The condition typically develops during puberty when young people’s bones are growing rapidly. Ewing sarcoma affects boys and people assigned male at birth (AMAB) more often than it affects girls and people assigned female at birth (AFAB).
