I was a military aircraft mechanic for 18 years. I had a spot on my forehead that would bleed for a few days and then stop. I went to a PA who said that she did not think that it was skin cancer but she wanted me to go to a dermatologist because she was not an expert. It was skin cancer which was removed. A few years later I had a place on my nose do the same thing. It too was skin cancer and was removed.
