Itchy Nipples: What Causes Them and Which Nipple Rashes Need Prompt Evaluation
Nipple itch (nipple pruritus) is itching of the nipple and areola. Most cases are caused by dry skin, friction, eczema of the nipple (nipple eczema), contact dermatitis, or Candida yeast during breastfeeding. A red, scaly or weeping rash on one nipple that does not improve within 2–3 weeks needs to be examined to rule out Paget's disease of the nipple (Paget's disease of the nipple), a rare type of breast cancer.
Itching alone with normal-looking skin is almost never the first sign of cancer. What a dermatologist weighs most is how the rash looks, whether it is on one side or both, how long it has been there, and how it responded to anything already applied. This article goes through the causes one by one, including men and breastfeeding mothers, how to tell eczema from fungus, the medicines doctors use, and what happens at a visit.
Itchy nipples on one side or both: what it can tell you
Counting the sides is a starting point for thinking, not a diagnosis.
Both sides at once: usually dry skin, friction, eczema, contact dermatitis, or scabies.
One side, started only a few days ago: usually friction from a bra, a sore from the side the baby feeds on most, or a local infection.
One side for more than 2–3 weeks: a red, scaly, crusted or weeping rash should be examined, even though most causes are still not cancer.
Normal skin, only itching: usually related to dry skin, fabric, or hormonal changes.
Nipple itch from dry skin (xerosis)
What it looks like: itching that comes and goes, with dry, tight areolar skin and skin around the breast, fine scaling and no weeping. It is usually on both sides, often with dry skin on the arms and legs too.
Causes: dry or cold air, long hot showers, soaps that strip skin oils, and skin that gets drier with age.
Severity/urgency: not dangerous and can be managed at home with petrolatum or a fragrance-free moisturizer twice a day, which usually shows results in 1–2 weeks.
When to see a doctor: if it is still itchy after 2 weeks of treatment, the rash is clearly red, or you itch all over without a rash.
Nipple friction from running (jogger's nipple)
What it looks like: stinging, red, chafed nipples, sometimes with blood seeping onto the shirt. It can affect both sides and appears after long exercise.
Causes: a shirt rubbing the nipples repeatedly together with sweat. It is seen in long-distance runners, men and women, and in people who wear coarse shirts or bras with edges that cut into the skin.
Severity/urgency: not dangerous. Shallow sores usually improve in 3–7 days once the rubbing stops. Applying petrolatum before exercise and choosing smooth-textured shirts reduces recurrence.
When to see a doctor: if the sore has pus, swelling or increasing pain, or if a rash is still there more than 2 weeks after stopping exercise.
Eczema of the nipple (nipple eczema)
What it looks like: a red, itchy rash with poorly defined edges and scaling, with skin that thickens when scratched repeatedly. When very inflamed it may become wet and crusted. It usually starts on the areola and affects both sides.
Causes: allergic-prone skin (atopy), the same condition as atopic dermatitis. It is common in teenage girls with a history of eczema, asthma or allergic rhinitis, and can flare with sweat, coarse clothing, friction and breastfeeding.
Severity/urgency: not dangerous, but it disrupts daily life and can become infected again. When the diagnosis is right, it usually improves within 1–2 weeks of starting a topical medicine.
When to see a doctor: if it has not improved after a full 7 days of a mild topical steroid, if it is on one side only, or if it keeps flaring so that you have to apply treatment often.
Contact dermatitis of the nipple
What it looks like: a red, itchy, stinging rash, sometimes with small blisters. The shape of the rash matches where the substance touched the skin, such as the line of a bra edge, and it usually starts within 24–72 hours of contact.
Causes: laundry detergent, fabric softener, fragrance, moisturizers, clothing dyes, nickel from hooks or nipple piercings, adhesive tape, nursing pads, lanolin cream, and sometimes the medicine applied itself. Doctors explain this mechanism in detail in the article on contact dermatitis.
Severity/urgency: not dangerous. The rash usually settles in 2–4 weeks after you stop using the trigger. If you keep using it, topical medicine controls it only temporarily.
When to see a doctor: if you cannot find the trigger, the rash keeps returning, or a breastfeeding mother suspects an allergy to a nipple cream. The doctor may do a skin allergy test (patch test), read at about 48 and 96 hours.
Fungal infection of the skin around the nipple and under the breast (ringworm and Candida)
What it looks like: ringworm (tinea corporis) is a red ring with a clearly raised, scaly edge and a paler center that slowly spreads outward. Cutaneous candidiasis is a moist red rash in the fold under the breast, with small satellite spots around the main rash.
Causes: moisture, sweat, tight bras, excess body weight, diabetes, and earlier use of a topical steroid.
Severity/urgency: not dangerous but does not easily go away on its own, and ringworm can spread by contact with pets or another person's skin.
When to see a doctor: if you are not sure the rash is really fungal, if it has not improved after 2 full weeks of antifungal cream, or if you have diabetes. The doctor scrapes the skin and looks under the microscope with potassium hydroxide (KOH), which gives a result within a few minutes to a few tens of minutes.
Nipple itch while breastfeeding: Candida yeast
What it looks like: deep pink, shiny nipples, sometimes peeling, with itching and stinging on both sides and a sharp burning pain after the baby feeds. The baby may have white patches in the mouth that do not wipe off, or a bright red diaper rash.
Causes: Candida grows on skin kept moist by saliva and milk, especially when there are cracks in the nipple, after the mother or baby has taken antibiotics, or when the mother has diabetes.
Severity/urgency: not dangerous and most mothers can keep breastfeeding, but the mother and the baby's mouth must be treated at the same time to stop the infection passing back and forth. Also, much nipple pain during feeding comes from a poor latch or an inflammatory rash, so do not conclude on your own that it is yeast.
When to see a doctor: if nipple pain lasts more than 1 week, if there is no improvement after 7 days of antifungal treatment, or if the baby has white patches in the mouth and feeds less.
Itchy and painful nipples from a poor latch
What it looks like: cracked nipples with a sore at the tip or base, sharp pain when the baby starts to suck, and itching as the sore starts to heal. After the baby lets go, the nipple may look squashed into a wedge shape.
Causes: the baby does not take enough of the areola, an unsuitable feeding position, tongue-tie, or pump suction set too high. In some women the nipple turns pale and hurts after feeding because of blood vessel spasm (vasospasm).
Severity/urgency: not dangerous but it is an entry point for germs. The sore usually improves within a few days once the latch is corrected. Wiping with clean water and letting the skin air-dry reduces irritation.
When to see a doctor: if the sore has not improved in 1 week, has pus, or if the breast is swollen and red with a fever of 38.5 degrees Celsius or higher, which may be mastitis and needs a doctor within 24 hours.
Bacterial infection of the nipple
What it looks like: a wet rash, honey-yellow crusts, small pustules, and pain with swelling and redness around the sore.
Causes: Staphylococcus aureus entering through a crack, a scratch, or an eczema rash that has been scratched raw.
Severity/urgency: moderate. If treated late it can spread into cellulitis or a breast abscess.
When to see a doctor: see a doctor within 1–2 days, and come immediately if there is fever, a hot swollen breast, or a tender lump.
Grouped clear blisters on the nipple: herpes
What it looks like: clear blisters 1–3 millimeters across, grouped on a red base. Burning or pain comes first, before the blisters appear, then they break into shallow sores and crust over in 7–10 days.
Causes: herpes simplex virus, which can be passed on by direct contact with a herpes sore.
Severity/urgency: not severe in healthy adults but very dangerous for newborns. If the sore is on the breast or nipple, do not breastfeed on that side until the sore has crusted over and is completely dry, and wash your hands before touching the baby every time.
When to see a doctor: see a doctor within 1–2 days of noticing the blisters, especially for mothers breastfeeding a young baby.
Nipple itch during pregnancy
What it looks like: mild itching of the nipples, breasts and abdomen, with darker areolas and skin that looks tight. Some women leak yellowish colostrum from the second trimester.
Causes: the growing breasts stretch the skin, skin dries out easily, and hormones change. Generalized itching affects about 1 in 5 pregnant women. Existing eczema can also flare during this time.
Severity/urgency: mostly not dangerous. Petrolatum and a well-fitting bra help. An itchy rash with bumps along the stretch marks of the abdomen in the third trimester (polymorphic eruption of pregnancy) usually clears on its own within 4–6 weeks after delivery. But severe itching of the palms and soles without a rash, especially at night, may be intrahepatic cholestasis of pregnancy, which affects the baby.
When to see a doctor: tell your obstetrician within 24–48 hours if the palms and soles itch, the eyes turn yellow, or the urine is dark, so that bile acids and liver function can be tested, and ask a doctor before using any topical or oral medicine.
Whole-body night itching and bumps on the nipple: scabies
What it looks like: small red bumps and short wavy lines on the nipple and areola, between the fingers, on the wrists, armpits, navel and groin, with severe itching at night. People in the household often itch too. The nipple is a common site in women.
Causes: the scabies mite (Sarcoptes scabiei), spread by prolonged skin-to-skin contact. In a first infection symptoms usually start 4–6 weeks after exposure. Details are in the article on scabies and night itching.
Severity/urgency: not dangerous but spreads quickly within a household. Everyone living together must be treated at the same time, and bedding and clothes washed in hot water. Itching can continue for another 2–4 weeks even after correct treatment.
When to see a doctor: if you itch all over at night, others at home itch too, or new bumps appear after 4 weeks of treatment.
Paget's disease of the nipple
What it looks like: a red, peeling, scaly or weeping rash on one nipple only, usually starting at the tip of the nipple and spreading to the areola, with itching, burning or tingling. Some people have an inverted nipple, a raw eroded surface, or nipple discharge. The rash does not go away and may improve temporarily with a topical steroid, which is why it is mistaken for eczema.
Causes: cancer cells from the milk ducts travel up to the skin of the nipple. It accounts for about 1–4% of all breast cancers and is most common between ages 50 and 70. About 8–9 in 10 people also have cancer inside the breast tissue on the same side, and about half have a lump that can be felt.
Severity/urgency: high, but not an emergency within hours. It should be examined within a few weeks, because treatment and outlook depend on the cancer underneath. The main treatment is surgery together with a breast surgeon, which may remove only the nipple and areola combined with radiation, or remove the breast. A topical medicine is not a treatment for this disease.
When to see a doctor: a one-sided nipple rash that has not improved in 2–3 weeks means stop applying things on your own and see a doctor for a biopsy and mammography (mammography). If there is a breast lump, bloody nipple discharge, or a newly inverted nipple, come without waiting for the full time. A normal mammogram cannot rule this disease out. If the rash is suspicious, the biopsy result decides.
A non-cancerous lump and sore on the nipple: nipple adenoma
What it looks like: an eroded sore, crust or small lump on one nipple, itchy and painful, with fluid or blood seeping. It looks very much like Paget's disease.
Causes: a benign tumor of the milk ducts in the nipple (erosive adenomatosis). It is rare and usually found at ages 40–50.
Severity/urgency: not cancer, but it cannot be told apart from Paget's disease by eye, so a biopsy is always needed. Treatment is surgical removal.
When to see a doctor: the same as for any one-sided rash, that is, when it lasts more than 2–3 weeks or there is bleeding from the nipple.
A swollen red breast with orange-peel skin
What it looks like: one breast that becomes red, swollen, warm, itchy or heavy quickly over a few weeks, with thickened, dimpled skin like an orange peel (peau d'orange). Most have no fever, and there is often no clear lump.
Causes: infectious mastitis is the more common cause in breastfeeding mothers, but inflammatory breast cancer must be considered. It accounts for about 1–5% of breast cancers, where cancer cells block the lymph channels in the skin.
Severity/urgency: high. It should be examined within a few days.
When to see a doctor: if you have the features above, or if 7 days of antibiotics for mastitis has not helped, which calls for an ultrasound, mammography and a skin biopsy.
Itchy nipples in men
What it looks like: men also have nipples and milk ducts, so they can get these same conditions. The common ones are itching or chafing from running shirts and coarse T-shirts, eczema, ringworm on the chest, inflamed hair follicles around the nipple, and enlarged male breast tissue (gynecomastia) that is painful or itchy under the areola.
Causes: friction, sweat, excess body weight, some medicines such as those that affect male hormones, and liver or thyroid disease. Breast cancer in men accounts for about 1% of all breast cancers and is usually found at an older age. Paget's disease in men is very rare.
Severity/urgency: mostly not dangerous, but men often come late because they do not think they can get breast disease, and thin breast tissue lets disease reach the skin and muscle quickly.
When to see a doctor: a one-sided rash for more than 2–3 weeks, a hard painless lump under the nipple, an inverted nipple, or fluid or blood from the nipple should be examined without waiting.
How to tell eczema from fungus and Paget's disease
All three are red, itchy rashes in the early stage. The clues below are a starting point for thinking, and confirming the disease needs an examination.
Location: eczema usually starts on the areola and spares the tip of the nipple · fungus is usually around the areola or under the breast · Paget's disease starts at the tip of the nipple and spreads outward
Number of sides: eczema is usually on both sides · fungus can be either · Paget's disease is almost always one-sided
Edge of the rash: eczema has poorly defined edges · ringworm has a clearly raised edge with a pale center · Candida has small satellite spots around it · Paget's disease has a fairly clear edge and thickened skin
Response to medicine: eczema clearly improves with a steroid in 1–2 weeks · fungus improves with an antifungal · Paget's disease does not clear with either type of cream and may only improve temporarily
Confirming test: eczema relies on examination and history · fungus uses a skin scraping under the microscope · Paget's disease uses a biopsy
What happens if you use a steroid or antifungal for the wrong disease
Treating at home without knowing the disease makes the rash harder to diagnose, so know the effects of wrong use before you apply anything.
Steroid on a fungal infection: itching eases at first but the fungus grows. The rash spreads wider and its edge changes until the original look is lost (tinea incognito), and the doctor also finds the fungus harder to detect.
Antifungal on eczema: the rash does not improve, time is lost, and some people develop an allergy to the drug or the cream base.
Steroid on Paget's disease: the rash may fade temporarily so that the patient thinks it has gone. The cancer diagnosis is then delayed.
Combination creams with several drugs: creams that put a steroid, an antifungal and an antibiotic together make the disease harder to tell apart and raise the chance of contact allergy.
Strong steroid on thin skin: the skin of the nipple and areola is thin, and a strong drug or long use thins the skin and causes visible capillaries and stretch marks.
If you are not sure which disease it is, or you have applied treatment for the full time and it has not improved, stop applying it and come for an examination, and tell the doctor everything you have applied. For general principles of choosing a topical medicine, read how to choose an itch cream correctly
Medicines doctors use for nipple itch, by cause
This list explains the treatment approach. The choice of drug, dose and duration is up to the examining doctor, according to the diagnosis, pregnancy and breastfeeding.
Petrolatum: apply twice a day and before exercise, and continue as needed. It works when the source of friction and irritation is also removed.
Hydrocortisone 1% cream: apply a thin layer once or twice a day for no more than 7 days when self-treating. Breastfeeding mothers apply after feeding and wash it off before the next feed. Works well when the condition is truly an inflammatory rash. If it is not better after 7 days, the diagnosis needs to be reviewed.
Moderate-strength steroid such as mometasone 0.1%: prescribed by a doctor for a short period, usually once a day for 1–2 weeks, for thick or severely flaring rashes. Results depend on a correct diagnosis and tapering as scheduled, because the skin here is thin.
Tacrolimus 0.03–0.1% or pimecrolimus 1%: non-steroid topical drugs, twice a day for one to several weeks. Suitable for rashes that keep recurring. Results also depend on avoiding triggers. It may sting at first. Breastfeeding mothers must ask a doctor first and must not let the baby's mouth touch the medicine.
Clotrimazole 1% or miconazole 2%: twice a day for 2 weeks for Candida and 2–4 weeks for ringworm. Apply 2 centimeters beyond the edge of the rash and continue for about 1 more week after the rash has cleared. Breastfeeding mothers apply after feeding, and any leftover must be wiped off before the next feed. Results depend on finishing the full course even after the itch has gone, and on treating the baby at the same time when breastfeeding.
Terbinafine 1% cream: once or twice a day for 1–2 weeks for ringworm. Oral tablets of 250 milligrams a day for 2 weeks are used for widespread rashes, and oral antifungals are generally not used in pregnant or breastfeeding women. If it has not improved after the full time, the fungus needs to be confirmed again.
Nystatin liquid for the baby's mouth: use at the dose the pediatrician prescribes, together with treating the mother, and keep going for at least 48 hours after the white patches clear. It works better when both are treated and the pump or bottle nipples are washed daily.
Oral fluconazole: the doctor considers it when nipple Candida has not improved with topical drugs after a clear diagnosis. The dose and number of days differ from case to case, and other medicines taken together must be checked. If it does not improve, review whether it is really fungal.
Mupirocin 2%: apply 3 times a day for 5–10 days for shallow infected sores. If it is spreading, the doctor may give oral dicloxacillin or cephalexin for about 5–7 days. Results depend on also treating the crack or rash that caused it.
Permethrin 5%: apply over the whole body from the neck down, leave on for 8–14 hours, then wash off. Repeat on day 7. Everyone in the household must be treated at the same time. The doctor may give ivermectin 200 micrograms per kilogram, 2 doses 7–14 days apart. Most failures come from not covering the whole body or the household not being treated together.
Acyclovir: 400 milligrams by mouth 3 times a day for 7–10 days for a first herpes episode. Starting early, within 72 hours of the blisters appearing, works better.
Cetirizine 10 milligrams: taken once a day it relieves itching to some extent. The effect on eczema is modest and it can cause drowsiness. Pregnant and breastfeeding women should ask a doctor first. More detail is in which oral antihistamine suits you
The rule that applies to every medicine in this list: a one-sided rash that has not improved in 2–3 weeks must not be treated on your own any longer.
What to expect at a visit for nipple itch
Most examinations are not complicated and do not take long. The usual steps are in this order.
History: how many weeks it has lasted, one side or both, what you have applied, whether you are pregnant or breastfeeding, any allergy history, regular medicines, and any family history of breast cancer.
Skin examination: looking at the nipple, areola and surrounding skin, and comparing both sides. The doctor may use a skin scope (dermoscopy) and check other areas of the body for the same type of rash.
Feeling the breast and armpit: looking for lumps and enlarged lymph nodes, which is routine for a one-sided rash.
Skin scraping under the microscope (KOH): when fungus is suspected. It is painless and gives a result within a few minutes to a few tens of minutes. If the sore has pus, the doctor may swab it for culture.
Skin allergy test (patch test): when contact allergy is suspected. Test patches are stuck on the back and read at about 48 and 96 hours.
Skin biopsy: used when a one-sided rash does not improve or looks suspicious for Paget's disease. The doctor numbs the area with local anesthetic, then takes a skin punch of about 3–4 millimeters and closes it with 1–2 stitches, or may take a small wedge from the nipple. It does not take long, and the pathology result usually comes in 5–10 working days, which may be longer if special stains are needed.
Breast imaging: when the biopsy shows Paget's disease or there is a lump, a mammogram, ultrasound and in some cases an MRI are done, and the patient is referred to a breast surgeon to plan treatment.
If you have applied medicine before, bring the tubes or photos of the labels, and if the rash improved temporarily with a drug, tell the doctor, because this affects how the findings are read. A rash that has been checked and is not cancer still needs follow-up to the end. If the medicine does not work, the doctor will review and can take another biopsy.
Self-care while waiting for the rash to improve
Wear smooth cotton bras of the right size and change right away after sweating.
Wash clothes with fragrance-free detergent and skip fabric softener while there is a rash.
Wash the nipples with plain water only, with no scrubbing, no alcohol and no harsh soap.
Pat dry after bathing before putting on a bra, and change nursing pads when they get wet.
Keep fingernails short to reduce damage from scratching.
Take a photo of the rash every week so the doctor can see the change.
In short
Most nipple itch comes from dry skin, friction, eczema, contact allergy and fungus. Itching alone on normal skin almost never points to cancer.
A breastfeeding mother with Candida must be treated together with the baby's mouth, and most can keep breastfeeding.
Men can also get nipple disease, including breast cancer, which accounts for about 1% of all cases.
A steroid on fungus makes the rash spread, an antifungal on eczema does not work, and a steroid on Paget's disease delays the diagnosis.
A red, scaly or weeping rash on one nipple that has not improved in 2–3 weeks means stop applying things on your own and have a biopsy together with a mammogram.
A breast lump, bleeding from the nipple, or a newly inverted nipple should be examined without waiting for the full time.
Frequently asked questions about itchy nipples
What causes itchy breasts?
Itching of the breast and nipple is mostly caused by common skin conditions. The most common are dry skin, friction from a bra or workout clothes, eczema, contact allergy to detergent or fragrance, fungus under the breast, and skin stretching during pregnancy. If it itches while the skin still looks smooth and normal, switch to soft clothing and apply petrolatum twice a day for about 1–2 weeks. But if there is a red rash, peeling skin, weeping, or a lump you can feel, have a doctor examine it, because the medicine for each cause is very different and using the wrong one can let the rash spread.
What causes one itchy breast?
If it started only a few days ago, the cause is usually friction from a hook or bra edge, a sore from the side the baby feeds on most, or a localized contact rash, which usually improves once the trigger is removed. But a red, peeling, crusted or weeping rash on one nipple for more than 2–3 weeks should make you stop applying medicine on your own and have a doctor examine it, to rule out Paget's disease of the nipple and a benign nipple tumor. Both are rare and cannot be told apart by eye. A small biopsy under local anesthetic is the way to get a clear answer.
What kind of itching is cancer?
Itching alone almost never means cancer, and most people with long-term itching have other causes such as dry skin, eczema, medicines, kidney disease, liver disease, or thyroid problems. What should be examined is itching that comes with other signs, such as a one-sided nipple rash not improving in 2–3 weeks, a breast lump, bleeding from the nipple, a mole or sore that changes shape, or whole-body itching for more than 6 weeks without a rash together with weight loss, fever, night sweats or yellow eyes. Blood tests and a physical examination can usually give the answer without complications.
What kind of itching is lymphoma?
Itching from lymphoma is usually widespread and long-lasting, not limited to the nipple. Most often there is no obvious rash apart from scratch marks, and it tends to be worse at night. It is seen in about 10–30% of people with Hodgkin lymphoma. What makes a doctor investigate further is painless lymph nodes in the neck, armpit or groin that are enlarged and do not shrink, together with long-lasting fever, night sweats that soak the clothes, or weight loss of more than 10% in 6 months. If the itching is alone and none of these are present, the cause is usually a common skin disease.
Is itching normal in pregnant women, at the nipples and breasts?
Mild itching of the nipples, breasts and abdomen is common during pregnancy because the skin stretches, dries out easily, and hormones change. Applying petrolatum twice a day, bathing in water that is not too hot, and wearing a well-fitting cotton bra usually help. What should not wait is severe itching of the palms and soles without a rash, especially at night, or itching together with yellow eyes and dark urine, because it may be cholestasis of the liver, and you must tell your obstetrician within 24–48 hours for blood tests. Ask a doctor before using any topical or oral medicine.
Can I treat itchy nipples myself? What if it does not go away?
You can apply petrolatum freely, and for a bilateral itchy rash with no sore you may apply a thin layer of 1% hydrocortisone once or twice a day for no more than 7 days. If it does not improve, stop applying it, because the rash may be fungal, a disease that does not respond to steroids, or an allergy to the drug. Do not use combination creams with several drugs without knowing the disease. At a visit the doctor examines the skin, scrapes the skin for the microscope if fungus is suspected, and takes a biopsy if a one-sided rash is not improving, so it is clear how to treat it.
