Breast rash

Development of a blister or rash, change in skin color, tenderness of the skin, and inflammation may indicate breast rash. Bacterial infections, allergies, dermatitis are some of the common causes of forming a breast rash. However, it is important to rule out the possibility of breast cancer

What are the most common causes of developing a breast rash?

Many common causes can cause breast rash, such as,

  1. Dermatitis: A condition that causes inflammation of skin, dryness, blisters, and a red rash.
  2. Heat Rash: An exposure to excess heat may cause heat rash to develop on the breast. 
  3. Yeast infections caused by candida fungus can cause a rash on the breast or even other body parts. Hot and humid weather in summer often causes perfect conditions for fungal infections. 
  4. Insect bite: Rashes are commonly developed due to insect bites. The affected area may turn into a rash or crusty blister. 
  5. Allergic reaction: Certain food allergies, irritants may cause body rashes. Certain dyes in clothes, beauty products may cause allergic reactions. 
  6. Psoriasis: This condition can cause itchy, scaly patches on the skin. It commonly occurs on the elbows, scalp, and back. 
  7. Cellulitis: Deep bacterial skin infection may cause oozing blisters and rashes on your body. 
  8. Nipple eczema: Nipple eczema can cause rashes around nipples that are dry and scaly.
  9. Breast Abscess: Abscess is developed when a lump with pus is formed under the skin. It is painful and may drain pus from the affected area. 
  10. Intertrigo: Excess sweat, friction, poor circulation, hot temperatures, and skin rubbing on cloth, may cause a red rash, especially around skin folds. Certain fungus strains are responsible for this condition. 
  11. Inflammatory breast cancer (IBC): IBC is an hostile breast cancer that develops when the cancer cells get into your lymph vessels draining the skin of your breast. When the lymph vessels become blocked by cancer cells, symptoms start appearing. These include:
  • Thickened skin
  • Rash or irritation that look like an infection
  • Red, warm and swollen breast
  • Pitted skin on breast, resembling an orange peel
  1. Mastitis: It is a painful swelling of the breast that most often occurs in breastfeeding women, generally within three months of giving birth. The infection occurs when milk builds up inside your breast owing to a clogged duct or some other factor which slows or prevents milk flow. 
  2. Mammary duct ectasia: This is a benign (non-cancerous) condition that occurs when a milk duct in your breast widens and its walls get thickened. 
  3. Paget’s disease of breast: This is a rare form of breast cancer – 1 – 4 per cent of all cases of breast cancer. It involves the skin of the nipple and can extend onto the areola, the dark-colored skin around nipple.
