Pain around the tumor is a major symptom, and there is often a lump or swelling around the site as well. Fatigue, fever, and weight loss are other symptoms.
What causes the Ewing family of tumors?
Medical professionals are unsure of the exact cause of this cancer; they know that changes in the DNA lead to cells growing and multiplying rapidly until they form a tumor. They have also discovered sporadic chromosomal mutations that play a role: changes in the EWSR1 gene on chromosome 22. More research needs to be done to understand how this change leads to cancer.
Risk factors include being white, being male, and being a teenager.
