So recently this mole appear on my upper back and it's fairly big, I would say about 1 cm, could be a bit bigger. And I don't have any other moles on my back at all. You know it's really quite annoying cause it's right in the center almost between my shoulder-blades, but it doesn't hurt or anything and I don't believe any hair is growing out of it or anything. What's your guys opinions about this?
