Normal Variation Is Wide
Nipples vary enormously — in size, shape, color, and orientation. Inverted, flat, and protruding are all within normal range, as is one nipple looking slightly different from the other. Hair around the areola is normal. Small bumps on the areola (Montgomery glands) are normal. The useful skill isn't matching yourself to some ideal — it's knowing your own baseline well enough to notice a genuine change.
Changes Worth a Prompt Check
- New inversion of a nipple that was previously not inverted
- Discharge that's spontaneous (not from squeezing), bloody, or from one side only
- Persistent skin changes — scaling, crusting, redness that doesn't resolve
- A noticeable, new change in size, direction, or shape
Paget's Disease of the Breast
This is a rare, specific condition worth knowing the name of: it presents as nipple skin changes that look a lot like eczema — scaling, redness, crusting, sometimes itching — and it's associated with underlying breast cancer in most cases. It's easy to mistake for a skin condition and treat with cream, which delays diagnosis. The distinguishing clue is that it doesn't improve with standard eczema treatment. Any persistent nipple skin change that isn't resolving deserves evaluation with this specifically in mind.
