A few months ago I discovered a new mole (at least I think it was new, or maybe it just became a bit more raised) on my forearm. The mole was light brown. This summer, however, the mole has turned pink. And now there is a white rim around it (the skin around it is not tan like the rest of my arm).
So this is a pink mole, 5mm in diameter, with a white rim that is 8mm in diameter.
What would you think this could be?
I am going to see a doctor, and I have an appointment at the beginning of September (regarding a different issue). That is a month from now. Will this be too long to wait, and should I try to get a doctor's appointment sooner?
