Breast Rash – Symptoms

We Primary Care - Best Primary Care Knowledge Site


Breast rash refers to the redness and discomfort of the skin on the breast. A breast rash may be itchy, scaly, painful, or blistering.

A rash on the breasts is often referred to as dermatitis, a disease comparable to hives.

If you have a sensitive region or rash on your breast, it may be a symptom of something more severe, such as an infection. Some of these instances may be caused by a common and curable skin disease, while others may just be a symptom of that illness.

Inflammation-related breast cancer spreads rapidly after diagnosis, usually within weeks or months. It may manifest as an odd rash, pain, and other symptoms.

A rash on the breast with persistent itching can be a sign of breast cancer. However, a red rash on the breast that is not itchy can be due to other conditions, like allergies.

Acne, inflammation, redness, and other color changes in the skin are all signs and symptoms of a rash. Women must get their breasts checked by a medical expert promptly in order to identify whether they have a common skin condition or a more severe illness such as breast cancer.


A rash on the breasts may occur for a variety of reasons. Two of the most common causes of this symptom are infections and allergic responses. Even though it is very uncommon, this may be a symptom of breast cancer or Paget’s disease of the nipple, or inflammatory breast cancer.

Medical disorders that cause rashes elsewhere on the body, such as an infection or an allergic response, are the most frequent cause of skin rashes. Certain rashes, however, appear solely on the breasts in some people.The same variables that produce other kinds of rashes also cause breast rashes. Some rashes only appear on the breasts in rare cases and may be caused by a number of causes, including the following:

·         Breast abscesses caused by infections

·         Breast cancer rash can occur in case of breast cancer

·         Persistent inflammation in the breast tissue may lead to inflammatory breast cancer rash

·         Ectasia of the mammary duct occurs when the mammary duct is obstructed, as in a breast cancer patient

·         Mastitis is a disease that affects the breasts causing a red rash under the breast

·         Nipple dermatitis is a kind of dermatitis caused by a bacterial infection that affects the skin

·         The skin condition intertrigo leads to the development of rash between breasts. It may give rise to an itchy rash.

·         Fungal rash on the breast may develop due to a yeast infection

A breast abscess is a bacterial infection that causes pus to accumulate under the breast surface. Breast abscesses are often linked with untreated mastitis and mainly affect breastfeeding moms. The most common cause of mastitis or breast abscess in women who do not breastfeed is duct ectasia (enlargement of the ducts under the nipple). The ducts beneath the breast enlarge and act as a breeding ground for germs in this condition.

The following are some of the most frequent causes of rash on any part of the body, including the breast:

·         Atopic dermatitis or eczema

·         Candidiasis is a common disease that may be passed from person to person (especially rash under the breasts)

·         Cellulitis

A heat rash under the breast may develop rapidly and cause pain. Unusual sweat gland activity in the underarm region, which may occur in places with high temperatures and humidity, can result in an underarm heat rash. Sweating into the skin tissues happens when sweat glands get blocked, enabling sweat to permeate the skin and enter circulation. A heat rash on the breast can also occur because of this phenomenon.

When to see a doctor

The following are signs that you should visit your doctor right away:

·         Fever and excruciating pain

·         Your breasts are red-striped.

·         Pus with a yellow or green color

·         Sores that have not healed

You should also contact a doctor if any of these symptoms worsen. They will examine you to identify the source of your rash so that you may get the most suitable treatment. Some mild rashes may be treated quickly and successfully with a particular cream.

If you do have a breast infection, you will need medications to treat it. Even if you start feeling better right, stick to your prescription schedule.

You will not be forced to stop nursing unless your doctor recommends otherwise. Empty your breasts fully to decrease your chances of developing an abscess, which is a pus-filled pocket that may need draining.
