An osteochondroma is the most common type of harmless bone tumor. It starts in the cartilage that cushions bones. It can appear on the bones of the arms and legs. Sometimes it happens on the pelvic bones and shoulder blades.
An osteochondroma usually stops growing when a person reaches full height. If the tumors are harmful, they will keep growing and spreading.

You will be asked about your child's symptoms and health history. Your answers and a physical exam may point to osteochondroma. They may also have:
Imaging tests such as:
- CT scan
- MRI scan
Your child's doctor may do a biopsy . A tissue sample is taken and checked in a lab. This will determine if the lump is cancerous.
Your child's doctor will go over treatment options. These may be:
- Monitoring—If the lump is not causing pain or other problems, it may be left alone. You and the doctor will keep track of it for any changes or new problems.
- Surgery—The lump is removed if it causes pain or other complications. It’s also removed if there is a chance of cancer. If the bone is weak, it can be rebuilt. Rebuilding the bone is done over a long period of time.
