While I was pregnant I went to doctors about a lump in my right breast he said it was calcium build up. I'm just wondering if this could have anything to do with whatever it is that squirts from my nipples when pressed. I never breast feed but I did have a hard and long labour of 42 hours first baby but she is 14 months now.

You might benefit from a mammogram and, if there is a lump, a fine needle biopsy to rule out breast cancer.
