About 8 years ago I noticed I had a growth on the center of my forehead. It grew over the years and I finally went in to have it Xrayed. They said it was just bone, but the bone has grown and seems to continue to grow. In is in the center of my forehead and looks like a horn or something. It is in fact bone.

Is this something a doctor or anyone can fix? Since I didn't have it before is it something that can be removed? Does anyone know? Please help. It is really noticeable and is starting to really bother me.
