At least every month or every other month a hole opens up on my nipple and i can see a little bit of the skin inside my nipple this causes a lot of pain to my boob. I have a group of bumps under my right boob and a lump near the bottom of my right and left boob. Do I have breast cancer PLEASE answers. I'm very concerned because I don't know what's happening and I don't know if this is normal. Should I see a doctor?. Is it possible to know if I have breast cancer this young?
