Hi, 38 Year old male, 185 lbs, healthy and fit . For about a year or more now i have been able to regularily squeeze small amounts of a white substsance from a spot beside my right nipple. I noticed a small lump a couple of years ago, and when suezzed the whie cheesy like substance came out. It is not sore,but I can feel a small tube like canal from the spot underneath the flesh. i have googled this and came up with several answers. Any thoughts would be appreciated. And no, i have seen a Doctor for this, guess i should.
