When I get out of the bath mainly, I notice dry skin that can be peeled off on the tip of my nipple. It is only on one nipple. I've had it for quite a while but only recently found out it could be cancer. I'm really worried. Is there anything else that could be causing this dry skin? My boyfriend always sucks on them I don't know if that will affect them. Also, I know it's gross but I only have a few bras so sometimes I end up resulting in Wearing the same bra for more than one day. I'm only 17 and I'm prettified and embarrassed to visit a doctor.
