Pimple With Pus On Breast. Pimples form when pus gathers near or on the skins surface. I FINALLY pushed on it and it literally exploded with pus blood and God only knows what else.

Its been almost 24 hours and it doesnt hurt as bad but. An abscess is created when pus builds up in an enclosed area of tissue. Swelling of the breast.
The pimple is swollen larger then the actual nipple and extraordinarily painful.
Pimples under the breast are more likely to be caused by fungal infections but when they are on the skin on top of the breast appear black or dark feel hard and recur they could be signs of breast cancer. Small cracks develop in the skin of the breast and nipple allowing Staphylococcus aureus bacteria to enter the body. Same goes for a pustule. Not only do these lumps look quite a bit like pimples they can also ooze pus.
