  • Chafing between the skin folds which can be caused by wearing a tight bra.

Dr. Tim Kenny on says that a candida skin infection can also cause inflammation under the breast.2 This is sometimes referred to as candida intertrigo, and it can cause some breast soreness and a yellow-like substance to develop over the affected area.

One of the most common reasons for a rash under the breast is wearing a wrong fitting bra. Dermatologist Dr. Graham Johnston told the Daily Mail newspaper that a badly fitting bra can cause the skin to chafe. This can result in an itchy rash because of the sweatiness and chafing. This can then lead to further infections.3

Also, women who are overweight or have diabetes can also be more prone to developing infections under the breast.4
