Osteoid osteoma is a tumor and it does sound scary. However, it’s not something that you need to be scared of because osteoid osteoma is a benign tumor, which means it is not cancer. It is also very rare that it ever develops into something more serious.
Surgery is the recommended treatment for osteoid osteoma so the surgeon can go in and be sure that the whole thing is removed. The size of the mass is usually less than a centimeter, but it can cause a lot of pain for the person who has it.
