Scabs on your nipples almost always form for the same reason scabs form anywhere else on your body: the skin has been damaged, and your body is patching the wound. The most common culprits are friction from clothing, breastfeeding-related trauma, and flare-ups of ordinary skin conditions like eczema or psoriasis. In rare cases, though, a persistent scab that won’t heal can signal something more serious, including a form of breast cancer called Paget’s disease. Understanding the likely causes and the specific red flags worth watching for can save you both unnecessary worry and dangerous delay.
Friction and Chafing
If you’re not breastfeeding and your nipples have developed raw patches or scabs, the simplest explanation is mechanical friction. Runners know this well enough to have given it a name: “jogger’s nipple.” Repetitive rubbing from a shirt, sports bra, or even a seatbelt strap can abrade the delicate skin of the nipple until it cracks and bleeds. The scabs that follow are just your skin healing itself. This tends to happen more in cold, dry weather when skin is already less pliable, or during long endurance events when sweat and salt crystals make fabric more abrasive.
The fix is straightforward. Wearing moisture-wicking fabrics, applying a barrier like petroleum jelly or adhesive nipple covers before exercise, and choosing well-fitting bras that minimize movement all reduce the friction. Once the skin has scabbed over, keeping the area clean and moisturized helps it heal faster. If the scabs keep coming back despite these measures, something else may be going on.
Breastfeeding-Related Nipple Damage
Cracked, scabbed nipples are one of the most common complaints among breastfeeding mothers, and the cause is almost always related to how the baby latches. A shallow latch compresses the nipple against the hard palate instead of drawing it deeper into the mouth, which creates intense friction and pressure on a very small area of skin. One retrospective study of postpartum women found that poor latch or shallow attachment was present in roughly 57% of mothers who developed nipple fissures, compared with about 16% of those who did not. Pain during feeds showed a similar gap.
1PubMed Central. Associated factors of nipple fissures in early postpartum women: A retrospective case-control studyTongue-tie in the baby (where a tight band of tissue under the tongue limits its range of motion) is one well-known contributor to latch problems. A study of Portuguese newborns found that mothers whose babies had tongue-tie were more than three times as likely to experience nipple trauma and about 50% more likely to report breastfeeding pain.
2PubMed Central. Prevalence of Ankyloglossia in Portuguese Newborns and Its Effect on Exclusive Breastfeeding and Maternal Nipple Pain During Postpartum HospitalizationA simple release of the tongue-tie, called a frenotomy, often resolves the feeding difficulty and allows the nipple to heal. In one published case, a four-week-old with a short lingual frenulum was referred after persistent latch failure and maternal nipple pain; following the procedure, breastfeeding improved.
3African Journal of Paediatric Surgery. Ankyloglossia (tongue-tie)Even without tongue-tie, breastfeeding technique matters enormously. A lactation consultant can often identify positioning issues in a single session and suggest adjustments that let the nipple heal within days. If you’re breastfeeding and dealing with scabs, getting the latch assessed before trying anything else tends to be the most productive step.
Eczema and Psoriasis on the Nipple
Eczema (atopic dermatitis) is a common cause of persistent scabbing on the nipple that many people don’t immediately connect to a skin condition. The nipple and areola are particularly vulnerable because the skin there is thinner and more prone to dryness than the surrounding breast skin. When eczema flares in this area, it causes redness, scaling, and crusting that can look alarming. In one published case, a 14-year-old girl presented with a year-long history of scaling, crusting, and discharge from one nipple; the diagnosis turned out to be chronic nipple eczema, and it cleared up completely with a topical corticosteroid.
4PubMed Central. Nipple eczema in an adolescent girl presenting with persistent unilateral nipple dischargePsoriasis can also affect the nipples and areolae, though it’s less commonly discussed. One case report described a patient with erythema, excoriation, and scaly skin around the nipple and areola, along with stabbing pain. A biopsy confirmed pustular dermatitis consistent with psoriasis.
5Consultant. Psoriasis of the Nipples and AreolaeThe tricky part is that both eczema and psoriasis of the nipple can mimic more worrisome conditions, including Paget’s disease. If you already have eczema or psoriasis elsewhere on your body and the nipple symptoms behave the way your skin condition usually does (flaring in response to your known triggers, responding to your usual topical treatments), that’s reassuring. If the symptoms are confined to one nipple and don’t improve with standard care, a biopsy becomes more important to rule out other causes.
Infection After Skin Breakdown
Once the skin of the nipple is cracked or scabbed, bacteria can move in and complicate healing. Staphylococcus aureus is the organism most strongly linked to sore, cracked nipples in breastfeeding mothers, and research has demonstrated a strong correlation between the two.
6PubMed. The treatment of Staphyloccocus aureus infected sore nipples: a randomized comparative studySigns that a scabbed nipple has become infected include increasing redness spreading beyond the immediate wound, warmth, swelling, pus or yellow crusting, and worsening pain rather than gradual improvement. A bacterial infection of the nipple skin typically responds well to topical or oral antibiotics, but it needs to be identified rather than just covered with ointment and ignored. Herpes virus can also affect the nipple, particularly during lactation, and produces clusters of small blisters that eventually crust over. A review of breast and nipple skin conditions during lactation lists herpes alongside eczema, psoriasis, and mastitis as conditions that may arise or worsen while breastfeeding.
7PubMed Central. Breast and Nipple Dermatoses During LactationFungal infections (thrush caused by Candida) are another possibility, though the diagnosis is controversial and probably over-applied. Thrush of the nipple typically presents as deep, burning pain that persists between feeds, sometimes with shiny or flaky skin. If you suspect an infection of any kind, see your doctor rather than self-treating, because the wrong topical product can make some infections worse.
Nipple Piercings and Other Trauma
Nipple piercings are a well-documented source of recurrent scabbing. The piercing creates a wound through tissue that is constantly subject to friction from clothing, and the healing timeline is long, often six months to a year or more. During that time, scabs form, get knocked off, and reform repeatedly. A systematic review of bacterial infections associated with nipple piercings found that the most frequent complications were fluid collection, pain, redness, granulation tissue, and swelling.
8PubMed Central. Bacterial infections in patients with nipple piercings: a qualitative systematic review of case reports and case seriesIf you have a nipple piercing and the scabbing seems persistent or is accompanied by discharge, warmth, or increasing pain, an infection is the first thing to rule out. Removing the jewelry is sometimes necessary to allow an abscess to drain, though a piercer or doctor can advise based on the specific situation. Even fully healed piercings can develop irritation scabs from jewelry friction or an allergic reaction to the metal, particularly nickel-containing alloys.
Post-surgical scabbing is another category worth mentioning. Any procedure involving the breast, from biopsies to mastectomies to cosmetic surgery, can result in crusting around the nipple during healing. Documented complications of breast cancer treatment include partial nipple-areola complex ischemia, wound breakdown, and radiation-induced skin changes, all of which can produce persistent scabbing.
9PubMed. Hyperbaric oxygen therapy for complex wound management following breast cancer treatment: Single institution 10-year experienceRaynaud’s Phenomenon of the Nipple
This one catches many people off guard. Raynaud’s phenomenon, where small blood vessels overreact to cold or stress by clamping down and restricting blood flow, can affect the nipples. It’s estimated to affect up to 20% of women of childbearing age in some form, and when it hits the nipples, it causes intense pain along with blanching (the nipple turns white), followed by blue and then red color changes as blood flow returns. The repeated cycles of restricted blood flow and reperfusion can damage the skin surface over time, leading to cracking and scabbing.
10PubMed. Raynaud’s phenomenon of the nipple: a treatable cause of painful breastfeedingThe telltale sign is that the pain and color changes are triggered by cold. Stepping out of a warm shower into a cold room, or the cooling effect of evaporating breast milk after a feed, can set off an episode. If you notice your nipple turning white and becoming painfully sensitive in cold conditions, Raynaud’s is worth considering. In breastfeeding mothers who tried medication for it (a blood-vessel-relaxing drug called nifedipine), all experienced prompt pain relief in one published case series.
10PubMed. Raynaud’s phenomenon of the nipple: a treatable cause of painful breastfeedingWhen a Scab Could Be Paget’s Disease
This is the scenario that worries people, and it’s the reason persistent nipple scabbing should never be completely dismissed. Mammary Paget’s disease is a form of cancer that affects the skin of the nipple. It typically starts with what looks like a stubborn patch of eczema: redness, flaking, crusting, and sometimes oozing. The key difference is that it doesn’t respond to the treatments that would clear up eczema or psoriasis, and it tends to be confined to one nipple.
11PubMed Central. Mammary Paget’s Disease of the Nipple: Relatively Common but Still Unknown to ManyA case series examining skin diseases of the nipple and areola found that all Paget’s disease rashes occurred on one breast, most involved the nipple specifically, and about two-thirds of Paget’s patients had exudation or erosion.
12Frontiers in Medicine. Skin diseases of the nipple and areola complex: A case series study from ChinaPaget’s disease is rare compared with eczema, friction damage, or breastfeeding injuries. But the fact that it mimics common benign conditions is exactly what makes it dangerous. Published cases describe patients who were treated with topical creams for months or longer before anyone thought to biopsy the lesion. By the time Paget’s disease is diagnosed, an underlying breast cancer is present in the majority of cases.
The red flags that distinguish Paget’s from benign scabbing include:
- One-sided: the changes affect only one nipple, not both.
- Treatment-resistant: the scabbing and crusting don’t improve after several weeks of appropriate topical therapy.
- Progressive: the affected area gradually expands rather than shrinking.
- Nipple changes: the nipple may flatten, retract, or develop erosion that seems to eat into the tissue rather than sitting on the surface.
- Bloody discharge: spontaneous bleeding or blood-tinged discharge from the nipple without obvious trauma.
Any of these on their own warrants a visit to your doctor. In combination, they strongly argue for a biopsy. The earlier Paget’s disease is caught, the better the outcomes tend to be.
Caring for a Scabbed Nipple at Home
For ordinary scabs caused by friction, minor trauma, or breastfeeding damage, the evidence favors keeping the wound moist rather than letting it dry out. This may feel counterintuitive since many people grew up hearing that wounds need air to heal, but moist wound healing promotes faster regrowth of the skin’s surface layer. Hydrogel wound dressings applied to nipple wounds help maintain moisture, reduce the risk of bacterial infection, and provide immediate pain relief.
13PubMed. Nipple wound care: a new approach to an old problemPractical steps for healing a scabbed nipple at home include gently cleaning the area with warm water (no soap directly on the wound, as it can be drying and irritating), applying a thin layer of purified lanolin or a hydrogel pad, and protecting the nipple from further friction with a soft breast pad or loose clothing. If you’re breastfeeding, expressing a small amount of breast milk and letting it dry on the nipple between feeds provides a natural moisturizer. Avoid picking at the scab, which resets the healing process and increases infection risk.
Over-the-counter hydrocortisone cream can help if the scabbing is driven by eczema, but use it sparingly and not for more than a week or two without medical guidance. If the scab doesn’t start improving within a couple of weeks of good wound care, or if it worsens, that’s a reasonable threshold for seeing a doctor.
Conditions That Affect Both Nipples Versus One
Whether the scabbing is on one nipple or both provides a useful diagnostic clue. Bilateral scabbing, affecting both nipples, strongly favors benign causes. Friction from clothing hits both sides equally. Eczema and psoriasis tend to be symmetrical. Breastfeeding damage can affect both nipples, though one side often gets it worse depending on the baby’s preferred feeding position.
Unilateral changes, affecting just one nipple, raise the index of suspicion slightly. As noted in the case series from China, all Paget’s disease presentations were unilateral.
12Frontiers in Medicine. Skin diseases of the nipple and areola complex: A case series study from China The eczema case described earlier was also unilateral, which is one reason it prompted investigation to rule out other causes.4PubMed Central. Nipple eczema in an adolescent girl presenting with persistent unilateral nipple discharge A one-sided scab doesn’t mean cancer, not by a long stretch. Plenty of benign conditions present asymmetrically. But if you’ve had a persistent, treatment-resistant scab on a single nipple for more than a few weeks, that specific combination is worth getting checked.
Scabbing in Men and Non-Lactating Women
Most of the research on nipple scabbing focuses on breastfeeding mothers because that’s where the problem is most common and most studied. But men and non-lactating women get nipple scabs too, and the causes overlap substantially with the list above. Friction from exercise, eczema, psoriasis, piercings, and contact dermatitis from laundry products or body care products are all possible regardless of sex or lactation status.
Men are less likely to think of their nipples as a site that deserves medical attention, which can lead to delayed evaluation. Paget’s disease of the nipple does occur in men, though it’s much rarer than in women. The same red flags apply: a persistent, one-sided, treatment-resistant, slowly expanding lesion with erosion or bloody discharge needs a biopsy. Eczema around the nipple in men is sometimes mistaken for a fungal infection and treated with antifungal cream, which won’t help and delays the right diagnosis.
Contact dermatitis is worth singling out in this group. A new laundry detergent, fabric softener, body wash, or even a new shirt fabric can trigger an allergic or irritant reaction that zeroes in on the nipples because the skin there is more sensitive. If the scabbing started around the time you changed a product, switching back is the simplest diagnostic test.
Dry Skin and Seasonal Patterns
Not every nipple scab has a dramatic explanation. Simple dryness, especially during winter months when indoor heating strips moisture from the air, can cause the nipple skin to crack and form small scabs. This tends to affect both sides equally, responds well to a fragrance-free moisturizer, and recurs predictably with the seasons. Hot showers, which feel great in cold weather, make it worse by stripping natural oils from the skin.
People with a history of atopic dermatitis are more susceptible to this kind of seasonal cracking, even if they don’t have active eczema at the time. The underlying skin barrier dysfunction means their nipple skin is less resilient against environmental drying. A regular moisturizing routine, particularly after bathing, goes a long way toward prevention. If the cracking is deep enough to bleed, applying a thin occlusive layer like petroleum jelly at night and covering with a soft pad keeps the wound environment moist and protected while you sleep.
