Signs and Symptoms of a Yeast Infection Under the Breast

Considered an opportunistic infection, yeast (candida) preys on those dark moist folds of the body prone to friction. Candida favors the area under the breast. According to Current Medical Diagnosis and Treatment, because the signs and symptoms resemble those of other skin diseases, an accurate diagnosis requires a microscopic examination of a scraping from the infected area. A true diagnosis ensures the proper treatment.

Signs and Symptoms

Intense itching and burning occurs once the rash appears. Ointments and powders have little or no effect, and corticosteroid creams will generally make the rash worse. The skin becomes denuded, meaning that areas of deep red welt-like thicknesses will appear, and the skin will ooze a whitish curd-like substance. As it spreads, the rash becomes visible without having to lift up the breast.

The Diagnosis

Since many skin rashes resemble each other, their diagnosis depends on examination of the cells under microscope. The Color Atlas and synopsis of Clinical Dermatology states the yeast candida, a type of fungus, exhibits clusters of little buds and antenna-like protrusions called hyphae. If candida is confirmed, the treatment will include anti-fungal ointments and/or oral anti-fungals, such as fluconazole.

The Prognosis

Some cases clear quickly with treatment while others become persistent. Current Medical Diagnosis and Treatment 2010 states that successful treatment depends highly on the patient’s compliance. This means not only faithfulness in applying or taking the medicines but continuing to use the topical ointment for some time after the rash disappears. Though the rash clears, a few stray yeast organisms may remain and stir up another inflammation; therefore, continued use of the medicine for a time set by your physician will lessen the chance of re-infection.


Yeast needs a dark, warm and moist environment to flourish; it does not those places without those criteria. To reduce your risk of yest infection, use talc or powder under your breasts daily. Lessen the amount of perspiration under breasts by inserting cotton pad in each bra cup. Treat other body folds in this manner, such as in the groin or under the belly. See a doctor at any sign of a recurrence.
