Ewing tumors are uncommon, and there are no widely recommended screening tests for these tumors. (Screening is testing for cancer in people without any symptoms.) Still, in some cases Ewing tumors are found early, before they have spread widely.

The most common symptom of a Ewing tumor is pain in the area of the tumor. The tumor may show up as a lump or swelling on an arm, leg, or the trunk. Sometimes the lump feels warmer than the rest of the body, and in some cases the child may have general symptoms like a fever and not feel well.

Of course, children and teens may get sore or have lumps and bumps from normal activities. But pains or lumps that stay around for a long time should be checked by a doctor. The same is true if a lump feels warm and/or the child has a fever. The lump is more likely to be caused by an infection, but this also needs to be seen by a doctor right away.
