I have a light colored round flat birthmark/mole on my chest that had a whitehead spring up just underneath it weeks ago. I extracted it and it started healing when it swelled up again and got itchy. When I squeezed the mole blood burst from it. It started healing again and swelled up again. Same thing. It's now itchy again just below the mark and is started to swell again. I'm assuming this is just persistent cystic acne and not a skin cancer issue. But I don't know much about melanoma and since a mole is involved I am being cautious. Anyone have any ideas?
