Types of Bone Cancer
Bones serve various purposes in the body. They protect and support the organs in the body. For instance, the brain is protected by the skull and the lungs are protected by the ribs. Blood cells are made and stored in the bone marrow, the spongy and soft tissue that many bone have in their center.
Primary bone cancer occurs most commonly in the legs and arms, although it can also affect other bones of the body. Primary bone cancers are usually referred to as sarcomas, of which there are several types. Each type of sarcoma affects a different type of bone tissue, with the most common being: chondrosarcoma; Ewing’s sarcoma; and osteosarcoma.
Chondrosarcoma: This type of bone cancer occurs mostly in adults. It affects the cartilage, which is the rubber-like tissue that is around the joints.
Ewing's sarcoma: This bone cancer occurs most often amongst people between the ages of 10-25, with teenagers being most affected. It affects the shaft, or middle part of large bones. It usually occurs in the long bones of the upper arm and thigh and also the hipbones. It can also affect the ribs.
Osteosarcoma: This is the most common kind of bone cancer and it affects young people in the age group of 10-25 years. Males are more susceptible to it compared to females. Osteosarcoma usually begins where new bone tissue forms, at the ends of bones, as young people grow. The long bones of the legs and arms are usually affected by it.
Cancers like the above, which start in the bone, occur rarely. However, it is quite common for cancers to spread from the other parts of the body to the bone. This type of cancer is known as metastatic cancer. Around 80% of the metastatic cancers that affect the bone are due to primary carcinomas that affect other organs such as the prostate, breast, kidney, lung, stomach, pancreas, and thyroid. Each of these types of metastatic cancers, which affect the bone, is named according to the tissue or organ where the primary cancer occurs.
