question: I have a small hard lump in between my breasts.  It started out as what I believe is an ingrown hair.  It is located right where I would clasp my front closing bra.  I had used warm compresses until I was able to drain it but when it healed I was left with this lump.  I have had it for a couple of years now.  It doesn't hurt but I am wondering what it could be and if there is anything that can be done to make it go away.  I do have a Hx of acne and no Hx of breast cancer in my family.  I am 37, female, 5'5" and 160 lbs.
