It is a bone cancer that affects children and adolescents, mostly white.
It is formed as a result of a genetic alteration. Its most frequent location is at the level of the pelvis and femur.
It does not usually cause much discomfort at first, but sometimes there is pain and swelling of the affected bone for weeks, which will be larger and different in shape than the same bone elsewhere.
Diagnosis requires a medical history and a complete physical examination. The confirmation diagnosis is made with complementary tests such as X-rays, bone biopsy, bone gammagraphy, CT-scans and MRIs.
A paediatrician or traumatologist should be consulted to extend the study and indicate the treatment, which is usually surgery (less and less aggressive), chemotherapy and radiotherapy.
