I have these bumps on my chest and under the breast. I have had them for almost ten years. They almost look like black heads but very very deep ones. My ob/gyn wanted me to get a biopsy because she said she didn't believe it was acne or a breakout. I never did, but recently I had my family doctor look at it and she said she thought it could be a fungus since I have had it for long. Have you ever heard of anything like this?
