What should you know about raised bumps on nipple?

Raised bumps on a nipple may be normal areolar glands or irritated skin, but new, persistent, painful, or changing bumps should be examined. Identify whether the bump is on the nipple, the darker areola, or nearby breast skin. Areolar glands can look like small raised dots and may become more noticeable with hormonal changes, temperature, or pregnancy. A blocked pore, friction, eczema, or infection can also affect this delicate skin.

A bump around a hair-bearing edge may reflect folliculitis; heat and moisture can cause heat rash. Milia are small keratin-filled bumps, while lichen planus can cause itchy, inflamed skin. A symptom label alone cannot distinguish these from breast or nipple conditions, so the surface, discharge, tenderness, and duration guide the examination.

Avoid squeezing, piercing, or applying fragranced products. Wash with lukewarm water, pat dry, and reduce rubbing from tight clothing or an ill-fitting bra. If breastfeeding, mention cracked skin, feeding pain, or a blocked duct to a clinician. Do not apply medicated creams without advice, especially if the bump is close to the nipple opening.

Seek prompt medical assessment for a new one-sided bump, persistent crusting or scaling, nipple inversion, bloody or clear discharge, a lump deeper in the breast, marked redness, warmth, fever, or worsening pain. Urgent care is appropriate if redness spreads quickly or you feel acutely unwell.

Is this arising from the areolar glands, a hair follicle, or deeper tissue? Should I stop any skin products? Could breastfeeding, friction, or infection be contributing? What follow-up is needed if it remains?
