Bone tumor is a cancer of bones that begins in any bone in the body. It most usually affects the long bones that make up the arms and legs. There are various types of bone tumor. Some of the tumors occur primarily in children while other may only occur in adults.
The exact cause of most bone tumor isn’t clear. Doctors know that bone tumor begin as an error in the DNA of the cells. The error results in growing and dividing of the cells in an uncontrolled way. These cells continue to live rather than dying at the set time. The mutated cells accumulate forming a tumour that can invade nearby structures and spread to other areas and organs of the body.
This is a rare type of benign (non-cancerous) bone tumor that primarily affects the long bones. The formation of such a tumor in the distal end of femur (thigh bone) leads to intermittent knee pain that increases at night. These tumors are generally less than 1.5 cm in diameter. Osteoid osteoma may develop between 5 and 25 years of age, and is more prevalent in males.

The treatment choice for the bone tumor is based on the rate of the cancer, its stage, his age, the overall health status of the patient, and the preference.
Radiation therapy uses high power beams of energy such as X rays to kill cells that spread cancer or tumor. The patient is made to lie down on a table while a special machine moves around him and aims the energy beams at precise points on the body during this therapy.
It is often combined with radiation therapy before surgery to shrink a bone cancer to a more manageable size that enables the surgeon to do a limb-sparing surgery.
