I had raised splotchy bumps on my face for years and was always saying I was tired even if I had slept enough. One day I had to get my wisdom teeth out and there was one hole that just wouldn't heal.
My surgeon felt so bad he thought it was his fault. Then I asked if he thought it might be cancer. It ran in my family, and it would make sense if my immune system was down and the hole wasn't healing because of it.
So I got a biopsy from one of the bumps on my nose and low and behold it was cancer. I was around 22 I think when I found out. Fun times lol.
