Bone Cancer

Bone Cancer

A mass of unusual cells growing in a bone. Most bone tumours aren’t cancerous.
Causes of bone tumours include abnormal healing of an injury, inherited conditions and radiation therapy. They can also be caused by bone cancer or another cancer that has spread to the bone from other parts of the body.
A bone tumour may cause a painless mass. Some people have dull, aching pain. In some cases, minor injury causes a fracture near the tumour.
Treatments include surgery and radiation. Some non-cancerous tumours go away without treatment.

Where does bone cancer usually start?
Bone cancer can begin in any bone in the body, but it most commonly affects the pelvis or the long bones in the arms and legs. Bone cancer is rare, making up less than 1 percent of all cancers. In fact, noncancerous bone tumors are much more common than cancerous ones.

Is bone cancer curable?
The prognosis, or outlook, for survival for bone cancer patients depends upon the particular type of cancer and the extent to which it has spread. The overall five-year survival rate for all bone cancers in adults and children is about 70%. Chondrosarcomas in adults have an overall five-year survival rate of about 80%.

How long can you live with bone cancer?
Generally, bone cancer is much easier to cure in otherwise healthy people whose cancer hasn’t spread. Overall, around 6 in every 10 people with bone cancer will live for at least 5 years from the time of their diagnosis, and many of these may be cured completely.

Is bone cancer aggressive?
Osteoblastoma and giant cell tumor of bone may become malignant after starting as benign. They will usually become aggressive without spreading to distant sites and cause damage to the bone near the tumor. Examples of malignant primary bone tumors include: osteosarcoma.

Who is most likely to get bone cancer?
Chondrosarcomas develop most often in adults, with an average age at diagnosis of 51. Less than 5% of cases occur in patients younger than 20. Chordomas are also more common in adults. Less than 5% of cases occur in patients younger than 20.
