I Have A Small Bump On Top Of My Head-

I have a small bump on top of my head- normal border, no pain caused by this bump, and no drainage. Just noticed it a week or two ago. Had one of the ER MDs I work with look at it, and he says it looks like it could just be a fibrous change. Family doctor says it could be a cyst and nothing serious, looking for more opinions. No family history of skin cancer
