What are the symptoms of Ewing sarcoma?
Ewing tumors are often found when they start to cause symptoms. The symptoms of Ewing sarcoma depend on the size and location of the tumor. Symptoms also depend on if it has spread to other parts of your body.
These are some symptoms of Ewing sarcoma:
- Pain, tenderness, or stiffness in the bone or nearby tissues
- A lump or swelling (especially in the pelvic area, leg, or arm) that's often soft and warm
- A broken bone that happens without injury
- Fever
- Tiredness or weakness
- Weight loss
- Pain that is worse at night or may increase with physical exercise
- Weakness, numbness, or paralysis in the arms or legs. This is caused by a tumor in the spine.
- Shortness of breath. This is caused by cancer that's spread to your lungs.
When to see your doctor
Many of these symptoms can be caused by other health problems. But it's important to see your doctor if you (or your child) have these symptoms. Only a doctor can tell if you (or your child) have Ewing sarcoma.
