Bone tumours occur when the cells within the bone divide uncontrollably and form a mass of abnormal tissue or lump. Most bone tumours are benign (not cancerous). Benign tumours are not life-threatening and will not spread to other parts of the body. Depending on the type, treatment interventions for benign bone tumours can range from simple observation to surgical removal.
Unfortunately, not all bone tumours are benign. Some bone tumours can be malignant or cancerous. Malignant bone tumours can cause the cancer cells to spread to other parts of the body (metastasise). Typically, the treatment approach for malignant bone tumours include a combination of radiation, chemotherapy, and surgery.
Bone tumours can develop in any part of the bone (from the surface to the bone marrow) and can affect any bone in the body. A growing bone tumour, even a benign one can weaken the bone and destroy healthy tissues, making it more prone to fractures. Malignant bone tumours are either primary or secondary bone cancer. Primary bone cancers originally begin in the bone while secondary bone cancers began somewhere else in the body and spread to the bone.
