What is the cause of bone cancer?
The most common types of bone cancer vary according to age. Osteosarcoma and Ewing's sarcoma are the most common type in children, teenagers and young adults. Chondrosarcomas is more common in middle aged and elderly people. Other less common types include spindle cell sarcomas and chordomas. A risk factor is anything that can increase your chance of developing a disease. Different cancers have different risk factors. We don't know what causes most cases of bone cancer. But there are some factors that may increase your risk of developing bone cancer. Cancer occurs when the cells in a certain area of your body divide and multiply too rapidly. This produces a lump of tissue known as a tumour. The exact reason why this happens is often not known, but certain things can increase your chance of developing the condition, including:
- previous radiotherapy treatment
- other bone conditions, such as Paget's disease of the bone
- rare genetic conditions, such as Li-Fraumeni syndrome
- a history of certain other conditions, including retinoblastoma and umbilical hernia
Some non-cancerous (benign) conditions affecting the bones may increase your chances of developing bone cancer, although the risk is still particular, a condition called Paget's disease of the bone can increase the risk of bone cancer in people over 50-60 years of age.Rarer conditions that cause tumors to grow in your bones, such as Ollier's disease, can also increase your risk of bone cancer.
