Did you know?
What makes you develop a breast rash? Let’s dive deep into various causes.
Breast rashes are often linked to bacterial or fungal infections. Cellulitis, candidiasis, and herpes zoster are a few common examples of infections leading to breast rashes.
Bacterial infections can cause inflammation and discomfort under the breast. An example here is cellulitis.
Cellulitis is a skin infection caused by bacteria, often Streptococcus or Staphylococcus. It enters the skin through cuts, cracks, or other injuries, causing a red, swollen, painful rash under the breast. In severe cases, it might need oral or intravenous antibiotics.
Fungal infections can cause rashes under the breast. Yeast infections like candidiasis and dermatophyte infections like ringworm are typical offenders.
Candidiasis is a yeast infection caused by candida albicans fungus. The warm, moist space under the breast provides a perfect breeding ground for these fungi. This leads to a red, itchy rash. To treat candidiasis, doctors usually prescribe antifungal creams or oral medications.
Ringworm isn’t caused by worms despite its name. It’s caused by a group of fungi known as dermatophytes. These fungi infect the skin and cause a circular, scaly, itchy rash. Doctors generally recommend over-the-counter antifungal creams or prescribed drugs to treat ringworm in a few weeks.
Viral infections such as herpes zoster (shingles) and chickenpox can also cause breast rashes.
Herpes zoster or shingles is caused by the varicella-zoster virus. This is the same virus that causes chickenpox. Those who have had chickenpox in the past stand a risk of the virus getting reactivated and causing shingles later on in life. This can result in a painful, blistery rash, often affecting the breast region. Shingles are typically treated with antiviral drugs and pain management techniques as prescribed by the doctor.
Though chickenpox usually affects the entire body rather than just under the breasts, it can cause a red, itchy rash consisting of fluid-filled blisters. The best way to prevent chickenpox is by getting vaccinated or having had the condition before.
Allergies can cause skin rashes under the breast. Contact dermatitis is one such allergic reaction.
Contact dermatitis happens when the skin encounters an allergen, such as certain cosmetics, soaps, or nickel in jewelry. The resulting rash can be red, itchy, and inflamed. By identifying and avoiding exposure to the allergen, and the use of corticosteroid creams or oral drugs, healthcare professionals can manage contact dermatitis.
Autoimmune disorders occur when the body’s immune system mistakenly attacks healthy cells. They can also cause rashes under the breast. Conditions such as eczema, inverse psoriasis, pemphigus, and Hailey-Hailey disease can lead to rashes.
Eczema, also called atopic dermatitis, is a long-term skin condition. It is marked by patches of skin that become red, itchy, dry, and cracked. While it can affect any region of the body, it often appears in skin folds like under the breasts. Regular moisturizing, use of corticosteroid creams, and staying away from triggers are often suggested for managing eczema symptoms.
Inverse psoriasis affects skin folds, including the region under the breasts. This type of psoriasis typically involves smooth, red skin patches that may become irritated due to sweat and rubbing. Topical therapies like corticosteroid creams and managing environmental triggers may help manage this condition.
Pemphigus is a cluster of rare autoimmune diseases. They lead to painful blisters and sores on the skin, including under the breast. Treatment for pemphigus often includes corticosteroids and immunosuppressive drugs to help curb symptoms and reduce flare-ups.
Hailey-Hailey disease, or familial benign chronic pemphigus, is a rare gene-linked disorder. It results in a repeating blistery rash in skin fold areas like under the breast. While these rashes tend to disappear and return on their own, the use of antiperspirants, cool compresses, topical steroid creams, and, in severe cases, oral antibiotics may be suggested to ease the symptoms.
A common cause of underbreast rash is a heat rash. This happens when sweat gets trapped under the skin due to blocked sweat glands. This leads to small fluid-filled blisters and bumps, or red, itchy, slightly raised areas on the skin. To manage heat rash, keep the area cool, clean, and dry.
Hidradenitis suppurativa is an inflammatory skin condition that causes tense, deep bumps, and acne-like lesions in places with high sweat and oil gland activity. That’s also where skin touches the skin, such as under the breasts. Though the condition has no cure, topical, oral, and injected drugs may help manage the symptoms and avoid complications.
If one has nipple dermatitis (inflammation of the skin) or a fungal infection and is nursing, their prenatal care provider or a lactation consultant may be able to help them for the same. People who are nursing may have a different course of management than those who are not nursing. This is due to the likelihood of your infant given the medication you may take could harm your baby. Antiviral drugs, painkillers along with rest are used by healthcare professionals to avoid rashes brought on by viral infections like chickenpox, shingles, or measles.

While very rare, a breast rash that won’t go away or gets worse could indicate inflammatory breast cancer, which is a high-risk form of cancer that spreads quickly and needs prompt remedy. Like all types of breast cancer, early detection and treatment are key to the best possible outcome.
Intertrigo is a skin irritation that occurs in skin folds, like under the breast, due to sweat and rubbing. It causes a red, moist, and sometimes itchy rash, often accompanied by secondary bacterial or fungal infections. Good hygiene and keeping the area dry can often prevent this level of skin irritation.
Pityriasis rosea is a common skin rash. It starts as a big, scaly patch with a clear peripheral scale and is followed by smaller, oval-shaped patches. It usually improves on its own in a few weeks and generally has no need for treatment. However, if an itch ensues, over-the-counter creams and lotions may provide relief.
Sweating and moisture, as well as chafing and friction from clothes, can prompt rashes under the breast. Good hygiene, breathable, sweat-wicking clothes, and use of barrier creams or powders can stop these issues from happening.
The following table summarizes the potential causes, symptoms, and treatments of a rash under the breast.
Potential Causes | Symptom Description | Treatment Options |
Infections | Redness, swelling, itching, possible blisters or pustules | Antifungal creams, antibiotic ointments, and antiviral drugs |
Allergies | Redness, itching, inflammation | Corticosteroid creams, oral antihistamines |
Autoimmune Disorders | Dry, cracked, itchy skin patches | Topical creams, managing triggers |
Heat Rash | Small blisters/bumps, itchy raised areas | Cooling off, keeping the area dry |
Hidradenitis Suppurativa | Painful, deep lumps and acne-like lesions | Topical/oral/injected medications |
Inflammatory Breast Cancer | Persistent, worsening rash, swelling | Early detection, prompt medical intervention |
Intertrigo | Red, moist, itchy rash | Proper hygiene, keeping the area clean and dry |
Pityriasis Rosea | Large scaly patch followed by smaller, oval-shaped patches | Time, over-the-counter creams, and lotions for itch relief |
Other Factors (sweat, friction) | Redness, irritation from moisture and chafing | Hygiene, breathable clothing, barrier creams/powders |
Always remember any medications available over the counter must only be taken under the guidance of a doctor.
Recognizing specific symptoms can aid you in figuring out the cause of a rash under the breast:
Redness or changes in color often appear with most rashes as they inflame your skin.
Itching is another typical symptom linked to rashes under your breast. This is especially true with fungal infections or allergies.
Sensitivity or discomfort in the rash area may suggest certain infections or inflammation.
Swelling can show signs of an infection, inflammation, or a serious underlying health problem.
Depending upon the cause of the rash, in some cases, blisters or pustules could form.
Scaling or flaking skin may be typical for certain autoimmune disorders like psoriasis.
Oozing (weeping) and crusting can suggest an infection that warrants medical help.
To my knowledge, topical steroids and ruling out the cause of irritation are two ways to deal with itchy and red rashes under the breasts. This may include products like soaps or cosmetics that might cause allergies, specific kinds of clothing materials, or friction from a bra or clothing.

To figure out the exact cause of a rash under the breast, a healthcare professional must conduct a thorough check-up:
Initially, a doctor will observe the rash. They will note its looks, place, and accompanying symptoms.
A detailed medical history, which includes possible contact with allergens or infections, can help pin possible causes of the rash.
If a fungal or bacterial infection seems likely, a specialist may take a skin sample to test in a lab.
In rare situations, a skin biopsy might be done for a more serious disorder or to ensure a certain diagnosis.
An allergy may be tested for via blood samples or skin tests if the healthcare provider suspects one as the source of the issue.
Depending on the culprit, there are many ways to treat a rash under the breast:
Various creams and ointments can heal rashes caused by infections, allergies, and autoimmune diseases:
For more serious or widespread rashes, oral remedies might be needed:
The above medications are to be taken under the guidance of a doctor, always.
Along with medical treatments, certain home remedies and lifestyle changes may prevent or soothe rashes under the breast:
If the rash keeps coming back, is painful, or lasts long, you should consult a doctor. Also see a doctor if it comes with signs like fever, pus, or spreading redness. It’s essential to get an accurate diagnosis and appropriate treatment plan for your specific needs.
