When I was about nine, I first noticed a medium sized, raised, dark brown mole on my shoulder. Over time, it got lighter, but just recently I noticed it was really light. (Now it’s mostly pink with a brown circle in the middle.) It doesn’t look like melanoma – it’s not red or raw or scaly. It’s a normal mole that’s just getting smaller. I read that hormonal birth control can sometimes cause this. Should I just calm down or talk to a doctor?
