Bone cancer develops when bone cells start to multiply rapidly and in an unusual manner. This results in break down of the bone. These bone cancer cells may also travel by blood to other oarts of the body like lung and other bones.Bone tumours occur in two age groups. Children and adolescents and people above the age of 50 years. However it must be remembered that majority of the bony swellings are benign(non-cancerous). What are the Signs and Symptoms of Bone Cancer?The bone which is affected may start paining. The pain may be intermittent initially but can later become continuous as the disease progresses. The pain may be worse at night. There may be a swelling or lump in the area. The disease may weaken the bone to cause a fracture. All these symptoms can also be caused by conditions that are not bone cancer. So if you have these symptoms you must tell your doctor.What Can The Doctor Do?Your doctor can order an X-ray of the bone affected. If X-ray is suggestive of bone cancer other tests will be required. These include blood tests, imaging studies like CT scan and MRI scan to check the affected bone. A whole body bone scan or PET scan may required to see if the disease has spead to other parts of the body.A biopsy is required to check if it is actually cancer. The biopsy is sent to a pathologist to confirm the diagnosis. The biopsy should be done by an experienced onco-surgeon. A wrongly placed biopsy site can be disastrous for the patient.What Are the Treatment Options For Bone Cancer?Bone cancer if detected in time can be cured. The treatment consists of mainly Sugery and Chemotherapy. Surgery these days involves what is known as limb salvage surgery. This is when the surgeon removes part of the arm or leg where the cancer is growing without removing the whole limb. Chemotherapy is required before and after surgery in many cases. It helps in killing cancer cells which may have spread by blood in the body. With early diagnosis and prompt treatment bone tumour can be cured in a large number of case especially in early stages. There are no common risk factors to bone cancers. Exposure to radiation and a family history are a few known factors.The key to treatment of bone tumour is early referral to a specialist and management in a specilised oncology centre
