Hi, I'm a 36 male with no serious medical conditions but have had a slow growing painless hard lump (feels like bone) on my forehead for the past year and a half. It is now around 3cm x 2cm and the skin moves freely on top of it. I've had an x ray that has shown it isn't an exostosis but i am now really worried and wondered if anyone else had had the same issue and what it could be? I have an appointment with a bone/sarcoma oncologist and CT scan on Monday and just really scared as to what it may be.
