Bone Tumours

In bone tumour, growing tumour in time spreads into the health tissues and causes the abnormal tissues to replace the health tissues and it weakens the bone and results with pathological fractures. In most of the bone tumours the reason is not known. If necessary measures are not taken, they may cause functional dysfunction within the organ system and even to death.

Most of the bone tumours are benign and benign tumours do not threaten life. In malign tumours the cells may spread into the body and constitute metastasis. Cancers which start over the bone (primary) and cancers which start at another place of the body and locate over the bone (secondary) are different from each other.

Tumours which course malign are the following:

Metastatic Bone Tumours: These are malign tumours which jump over the bone from other organs.

Multiple Myeloma: Multiple Myeloma is the most frequently observed primary bone cancer. It is the malign tumour of the bone marrow. It may affect any of the bones and it is observed in patients in between 50-70 years old.

  • Osteosarcoma is the second most frequently observed bone cancer. It is usually observed in adolescence age and appears at the knee area.

Ewing sarcoma: Ewing sarcoma is frequently observed in between 5-20 ages; it forms bone destruction together with wide soft tissue mass.

Chondrosarcoma: Chondrosarcoma is a bone tumour type which appears in between 40-70 ages, in the hip area, pelvis and shoulders together with a mass.

It gives its symptoms in many patients with tumours with a constant and obtuse pain. The physical activities do not affect pain and the pains deteriorate at night. Pathologic fractures may appear and this increases the pain. Some tumours cause fever and night sweating. And sometimes they appear with a painless mass.

Although treatment of the benign bone tumours change according to the tumour type and age of the patient, in many cases observation is sufficient. In some of them medical treatment heals pain. And some cases they disappear spontaneously (especially in children). In some cases the physician may propose the tumour to be removed; and this prevents the possible pathological fractions. But in some tumour types the mass may re-appear even it is removed. Some of the benign tumours may transform into malign tumours in time.

In the treatment of the malign bone cancers the type and stage of the tumour is determining. The surgical treatment may be both only removing the tumour and removal of the tumour tissue together with the healthy tissue around it. In the treatment radiotherapy and Chemotherapy may be applied in conjunction with the other treatment methods.
