Re: Worried about a brain tumor
Well, you passed the brain tumor test as well. While you must realize that diagnostics is ultimately impossible via the internet, the lump described in your posting is likely a Fibroma, a mass of fibrous tissue that is well-circumscribed and non-tender. They are entirely benign. I am assuming that you had this lump examined while at your physician and if not, then the next time you visit, I would suggest that you merely have this confirmed.
You'll be fine.
