here are two types of bone cancer: primary cancer of the bone, rare, and secondary bone cancer or bone metastases, more frequent.

Primary cancer of the bone

Primary cancers of the bones are localized cancers in the bone, or its immediate periphery, which develop from bone, cartilage or fibrous. They are quite rare. The main ones are osteosarcoma, chondrosarcoma, the Ewing’s sarcoma and multiple myeloma . The secondary bone cancer , or bone metastases, are remote locations, in bone cancer in another organ: prostate , kidney, breast, thyroid, …


This is the most common malignant primary bone tumors. In most cases, it occurs in children and adolescents or young adults. Its cause is usually unknown. The tumor usually develops near the ends (metaphyses) of long bones located in the vicinity of the knee joint (femur, tibia) and shoulder (humerus). It is accompanied by persistent pain and swelling. Thirty new cases per year are recorded in our country.


It develops from the cartilage and bones reaches large as the femur, tibia or humerus, but it can also sit on the pool or on many other bones. It mainly affects adults after 30 years.

Ewing’s sarcoma

This type of cancer of the bone primarily affects children between 10 and 15 years , more rarely in young adults. Boys are slightly more affected than girls (1.5 / 1). It is characterized by a proliferation of small round cells growing in the central region of the bone. It is accompanied by persistent pain, swelling and sometimes of a fracture. The tumor involves with equal frequency short or flat bones (pelvis, ribs, vertebrae) and long bones (femur, fibula, tibia, humerus), usually on the shank of the bone (diaphysis) and their end ( metaphysis). Ten new cases are diagnosed annually.

Multiple myeloma

This cancer, also called Khaler disease, is characterized by a malignant proliferation of unknown origin, plasma cells (cells producing and secreting antibodies in blood plasma) in the bone marrow. The latter secrete substances that cause a progressive destruction of bone tissue. It usually develops in adults between 50 and 80 years . It is somewhat more common in men than in women.

The role of surgery

Surgery plays an important role in the treatment of most bone cancers . The combination of different treatments (chemotherapy, radiotherapy and surgery) and advances in surgery have reduced the use of amputation (only 5% of cases). The doctors shall whenever possible to bone reconstruction.
