Ewing Sarcoma is a rare and aggressive type of cancer that forms in the bone or soft tissue. it is most commonly found in the legs, pelvis, ribs, and arms, and it typically affects children and young adults.

Symptoms include persistent bone pain that worsens at night or with activity, swelling, and warmth over the tumor site. A limp or limited range of motion develops when a limb is involved. Fever, fatigue, and weight loss suggest systemic involvement. Pathologic fracture can occur with minor injury.
Symptoms include persistent pain, swelling, and tenderness in the area of the tumor, which often worsens at night. Fever, fatigue, and unexplained weight loss are also common systemic signs.
Diagnosis involves a combination of imaging tests (X-rays, Magnetic Resonance Imaging, CT scans) and a necessary biopsy to confirm the presence of the specific cancerous cells and genetic markers.
This cancer can directly impact eye health if the tumor originates in the bones surrounding the eye (the orbit). A tumor in the orbit can cause proptosis (bulging of the eye), double vision, pain, and, if severe, loss of sight due to pressure on the optic nerve.
No, it is a rare cancer, particularly in adults.
Yes, localized pain is the most common symptom, especially pain that wakes the patient up at night.
No, treatment almost always involves chemotherapy before and after surgery to target the cancer cells throughout the body.
See an orthopedic oncologist if you have a persistent bone ache or a palpable lump that is firm and fixed. Ewing Sarcoma often occurs in the long bones or pelvis. A "Sunburst" pattern on an X-ray is a classic radiological sign that requires immediate biopsy.
