Blood spots on the breast: what to check

The location is important: a spot on the outer skin differs from blood coming through the nipple. Check for a surface break, raised bump, flat purple dot, discharge, warmth, swelling, or a new change in breast shape.

Bra friction, sweating, shaving, and scratching can damage the surface or aggravate a pimple-like follicle. A small blood blister may follow pinching, while clusters of flat non-fading dots suggest leakage from tiny vessels under the skin.

Bloody nipple discharge is not a skin spot and deserves clinical assessment, especially when it occurs without squeezing or from one side. Persistent crusting, dimpling, a newly inverted nipple, or a lump also needs examination; these findings have several possible causes.

Rinse a superficial bleeding point with clean water, apply gentle pressure with clean gauze, and cover it if clothing rubs. Choose a supportive, non-chafing garment and avoid squeezing, needling, or applying strong acne products to broken skin or the nipple.

Record when the change began and photograph it for comparison. Book a clinician if the spot returns, will not heal, has no clear cause, or is accompanied by discharge, a lump, skin thickening, or enlarged glands in the armpit.

Seek same-day care for rapidly spreading redness, increasing warmth and swelling, severe pain, pus with fever, or feeling generally unwell, as these can signal a significant infection.

Get urgent help for bleeding that does not stop with firm pressure, a quickly expanding bruise, or widespread non-fading spots with fever or confusion. Arrange prompt breast assessment for spontaneous bloody nipple discharge.

Clarify whether the blood originates in the skin or nipple and ask if an examination of the breast and nearby lymph nodes is needed. Mention pregnancy or breastfeeding, recent trauma, skin treatments, medicines, and any family history relevant to breast disease.
