My husband has one on his nipple. He's embarassed to take his shirt off and when people see it they make fun of him. His has grown for several months now. It's not exactly huge but it does look like a zit ready to pop. It looks white and stretched and hard to the touch. He said it doesn't hurt though. He went to a specialist and they said it couldn't just be cut off. The doctor said it has a deep root so they'd have to take the whole nipple off, which my husband said he wouldn't do. The doctor said it would be fine to leave there. I hope this helps.
