my moms friends DS found out the other day they have what's called a CMN, a congenital mole Nevus. it's basically a pretty large birthmark that has a higher than normal risk of turning into melanoma at some point in your lifetime. I know it's a weird and unusual question but is it disqualifying, he asked me to see if I could help him find out information since I'm on the forum. I don't really see how it could be but i wanted to make sure.
