Yeast Infection Under Breast

Your healthcare provider will perform a physical examination to diagnose a yeast infection under your breasts. They may be able to diagnose a yeast infection by looking at the skin under your breasts. If you have a bright red rash, your provider may be able to tell it’s a yeast infection.

Your healthcare provider may want to collect a sample of the rash for testing. They may use a tongue depressor or scalpel to gently scrape some of the skin from the infected area. A pathologist will look at the sample under a microscope. This can help them determine the type of fungus that’s causing the infection.
