A typical symptom of Ewing’s sarcoma is pain, sometimes accompanied
by swelling, at the site of the tumor. Depending on the position of the
tumor and how nearly it is located to nerves, the pain can be quite severe.
Often, the tumor is located in the middle of the upper arm bone (the
humerus) or the upper leg bone (the femur), but tumors may also be
located in the area between the two hips (the pelvis), in the chest, or in
the back. A lump may appear at the site of the tumor, and the patient may
feel warmth at the site.
Besides these symptoms, a patient may experience a fever, fatigue, little
or no appetite, and weight loss. Occasionally, individuals with Ewing’s
sarcoma break a bone even though they have had no accidents or other
injuries that would cause a broken bone. Such a break happens because
the disease can weaken the bones. Sometimes, individuals have no other
symptoms of a tumor until a bone breaks, and this broken bone is what
leads a doctor to diagnose the tumor.
In addition, tumors that are located near nerves can cause patients
to feel numbness or tingling and can occasionally cause paralysis or
incontinence.
In some cases, individuals may have a tumor for many months before
it begins to cause symptoms, because a tumor starts out small and grows
over time. Individuals may have no symptoms when the tumor is small but
may begin to experience pain and/or swelling when the tumor get larger.
