Hi there,
A good year ago or so, while at a vacation I noticed a black / brownish (mainly black) spot on my right nipple, at first I freaked out a bit, however I assumed it was harmless. One year later though, at the age of 16, The spot is still there, and it has neither shrunk nor increased in size. Its about a pen sized spot, and I'm curios as to what it could be, and if I should consult a doctor regarding it.
Thanks a lot, Male 16.
