Hello, I have noticed a small white spot on the side of my left nipple in late May. It is a tiny (now more than 5 mm) but clearly visible white spot on the nipple. It looks like a pimple with no head. Firstly, I thought it was a pimple but it won't come to a head. I know I shouldn't, but I have tried squeezing it and nothing happens. There is no discharge from the spot. It is not painful unless I touch it. I hasn't changed at all since it first appeared. I tried using salicylic acid, tea tree oil, epsom salt, warm compresses for a couple of weeks but nothing helped, so I have now left it alone.
I had had a mammogram and ultrasound back in January when I was in my home country just as part of a check-up. A partially calcified fibroadenoma was noted in the left breast and some small cysts in both breasts. I had a follow up appointment with a breast surgeon and another ultrasound scan in mid June in the UK. The scan confirmed the fibroadenoma, I thought these appear to younger women, but surgeon and radiologist said it appears completely benign and doesn't need a biopsy. I also asked the surgeon about the spot and she didn't seem to find it at all worrying, said it's just a blockage. Her report wrote it's keratinaceous material in one of the duct opening which should go away by itself. She didn't prescribe anything about it. However, the spot has not yet gone away.
I am 42 years old and have never been pregnant. I am not on any hormonal contraception. The spot looks similar to milk blebs, most information about such spots that I could find mentions pregnancy and breast feeding. I also read that in rare cases it could result from a tumour pressing on a duct. I'm increasingly worried about it, I will book another appointment to get to the bottom of it. I'm not sure why the surgeon was so dismissive about it. The spot appeared overnight and hasn't changed at all since.
Otherwise, I feel fine, left breast is a bit more sensitive before periods, but other than this spot I can't notice other changes in the nipple or the skin of the breasts.
I should see a doctor again, but it would be good to know if there are any resources about such spots that don't focus on breastfeeding women. Has anyone on this forum noticed similar spots?
