Pronounced: Oss-tee-oh-kon-drome-aEn Español (Spanish Version)
An osteochondroma is the most common type of benign bone tumor. It arises from cartilage tissue in children and adolescents between the ages of 10 and 20, usually appearing on the long bones (arms and legs) and less often on the pelvic bones and wing bones (scapulae). An osteochondroma ordinarily stops growing when a person reaches full height.
Most tissue in the body can grow beyond normal limits and form a mass, also known as a tumor. Tumors come in two forms: benign and malignant. The malignancies which are referred to as cancer, rarely stop growing. The benign tumors reach a certain size and then stop.
Bones can host at least ten different benign tumors, some of which turn into cancers. Less than 1% of osteochondromas turn into a bone cancer called chondrosarcoma, usually in later years.
