Definition
Breast rash is a change in the color or texture of the skin on the breast. It can be due to irritation or disease. A breast rash can be itchy, scaly, painful or blistered.

- Nipple dermatitis
- Paget's disease of the breast
Causes of a rash on the breast that can also occur on any part of the body include:
- Atopic dermatitis (eczema)
- Candidiasis (especially under the breasts)
- Cellulitis (a skin infection)
- Dermatitis
- Hives and angioedema
- Psoriasis

When to see a doctor
Make an appointment
A breast rash is rarely an emergency. But make an appointment with a healthcare professional if your breast rash doesn't respond to self-care or if you also have:
- Fever.
- Severe pain.
- Sores that won't heal.
- Streaks coming from the rash.
- Yellow or green fluid oozing from the rash.
- Skin that's peeling off.
- A history of breast cancer.
Seek emergency medical care if your rash comes with:
- Difficulty breathing, chest tightness or swelling in the throat.
- A rapid worsening of symptoms.
Self-care for breast rash
In the meantime, you may find some relief from your symptoms with these measures:
- Take a cool bath or put a cool washcloth over the rash for a few minutes. Do this a few times a day if it helps ease your symptoms.
- Use a gentle soap in the shower to clean the area. After you shower, apply a gentle moisturizing cream free of fragrances. Do this while your skin is still damp. Don't use fragranced products such as body washes, soaps and creams on the rash.
- Take care of your skin. Don't scratch the rash.
- Think about recent behaviors that may have caused your rash. Have you tried a new soap? Have you been wearing scratchy clothing? Stop using any new products that may have caused your rash.
