It is a cancerous condition that attacks the soft tissue that surrounds the bone or the bone itself, mainly affecting the bone structure of the leg or pelvis, although it may appear in any other bone, affecting more frequently children and adolescents.
The origin of the cellular abnormality that causes Ewing’s sarcoma is not yet known, but it is believed to be due to a disorder in certain genes.
The major complications of this type of cancer are its probability of metastasis, generally spreading to other bones and the lungs.
Additionally, as with any other cancer, chemotherapy and radiotherapy treatments have significant side effects that will continue to affect the patient long after receiving them.
Types of Ewing sarcoma:
- Focused: Cancer stays where it started.
- Metastatic: Cancer spreads to other parts of the body, usually to the lungs and bone marrow. The ways cancer spreads are:
- When it invades surrounding tissues.
- Through the lymphatic system.
- It can reach any part of the body by entering the bloodstream.
- Relapsed: When cancer returns after its apparent cure. It can do it to the same place where it originated or in any other area.
