The short explanation
An itchy, red, scaly patch on the nipple is often eczema or irritation from soap, detergent, a new bra or friction. These usually improve once the trigger is removed and the skin is cared for. But a patch on the nipple itself that does not settle, keeps returning, crusts or bleeds should be examined by a doctor, because a rare kind of breast cancer called Paget's disease of the nipple can look like eczema. Eczema more often affects the darker skin around the nipple first and both sides; changes that start on the nipple of one breast and slowly spread are more worth checking.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- Tell the doctor what you have already used on the skin and for how long, whether the other nipple is affected, whether there is discharge, and whether you are breastfeeding, which can also cause nipple irritation or thrush.
- If the patch does not respond to simple treatment the doctor suggests, or the doctor is unsure, a small skin sample may be taken along with a mammogram or ultrasound.
- Buying strong creams without advice can mask the change and delay a proper check, so it is better to have it seen.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This cannot tell you whether the patch is eczema or something else. An examination, and sometimes a small skin sample, are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Does this look like eczema, or should it be tested?
- What should I stop using on the skin?
- If it does not improve, what is the next step?
- Do I need any breast imaging?
When to seek help
Clinician-approved guidance for this topic. When in doubt, being seen is never the wrong choice.
Book an appointment soon
- See a clinician within a couple of weeks if a nipple patch has not settled, or sooner if it crusts, bleeds or the nipple changes shape.
Raise it at a routine appointment
- Switch to a mild unscented soap and cotton bra while you wait for the appointment. You can ask for a woman doctor for the examination, and you can bring someone you trust into the room with you.
