What is a giant cell tumor?

Also known as: giant cell tumor of the bone, GCTOB.

A giant cell tumor is a non-cancerous tumor (benign) that grows at the ends of the body’s long bones. Most often, it appears on the ends of bones such as the thigh bone or shin bone where they join with the knee, but can also occur at the wrist end or shoulder end of the arm bone and other sites. Though they are benign they can cause problems to surrounding bones and tissues.
