Yeah I have been fishing in the sun my whole life, I am 24 years old now. I had this spot on my neck for like 3 years and didnt think anything about it, my mom finally talked me into going to the dermatologist, when I did it was a cancer spot, grant it it was a bassel cell which is the mildest form of cancer, but cancer is cancer and it could have grown. so I was 21 when i first noticed it. I am stricken to sunscreen the rest of my life. So if you have any spots, no matter the age, get it checked out.
