What is an osteogenic sarcoma? how does somebody get one?

Cancer of the bone: A sarcoma is a malignant (cancerous) tumor of the connective tissue, such as bone, cartilage, muscle, etc. Most cancers involve organs and are adenocarcinomas, breast, lung and colon for example. Some people have a genetic predisposition to develope this type of cancer, but usually it is a random cellular mutation which causes the disease.

Bone cancer: Osteogenic sarcoma, or osteosarcoma, is a rare cancer. It forms bone tissue (when examined under a microscope) and usually arises in bone around knee or shoulder. Rarely, osteosarcoma may arise in the soft tissues. Most of the time there are random mutations causing the tumor but in rare cases there is a genetic mutation predisposing the patient. It is most common in teenagers and young adults.
