Abstract

Bone cancer is a type of cancer that develops in the bones of the body. It can affect any part of the body but is most commonly found in the arms and legs, pelvis, and spine. Bone cancer can be primary, starting in the bone itself, or secondary, spreading to the bone from another part of the body. Primary bone cancer is rare, accounting for only 1% of all cancers. The most common types of primary bone cancer are osteosarcoma, chondrosarcoma, and Ewing sarcoma. Osteosarcoma is the most common type and usually affects children and young adults. Chondrosarcoma is more common in adults and develops in the cartilage cells of the bone. Ewing sarcoma is also more common in children and young adults and starts in the bone marrow. Secondary bone cancer is more common, with cancer that has spread to the bones being more widespread than primary bone cancer. Secondary bone cancer can come from any other type of cancer, but the most common types are breast, lung, and prostate cancers.
