Yeast Infection Under Breast

Just like any other skinfolds or moist regions of your body, the area under breasts is quite vulnerable as well. The yeast affecting this region of the body is known as intertrigo or yeast infection under breast. This area is one of those folds where most of the time it remains moist or sweaty. Since this area never gets the opportunity to dry, it easily becomes yeast infected. Fungal infections are common especially in areas like groin areas, feet region and so on. The area under the breasts, also known as inframammary fold, does not dry easily and therefore prevails ideal conditions for growth of yeast infection under breasts.

Types of Infection:

  • Yeasts: Candida yeast infection is one of the most common form of fungi causing infections in intricate regions. Generally, yeasts cause infections when the skin is not healthy and thin or torn or there are many open cuts exposed to dirt and unhygienic conditions. The Candida species is held responsible for this skin infection, therefore known as sub-mammary Candidiasis.

  • Dermatophytes are another cause which spreads the effect of the fungi in other parts of the body. These bacteria create a red ring like infection in the affected areas and hence are also known as ring worm.


Yeast infection under breast is quite common especially among those who are lactating (breast feeding). But recent studies are depicting that women who are not lactating are also getting this infection at an increased rate. A study was conducted by King Fahd University, in Alkhobar, Saudi Arabia. 76% of the patients were lactating and were with some type of infection whereas almost 24 % of the non-lactating ones showed similar signs as well. In the latter group, Peptococcusmagnus, Entrobacter cloacae and Mycobacterium were held responsible. Although yeast infection under breast is seen among some women who are lactating, it’s clear that women during the process of breast feeding have a higher chance of developing an infection of their breast than non-lactating women. However, this may be due to fluctuations in the hormone balance or even keeping poor hygiene, more research still needs to be carried out on this.


Who Are Most Affected?

Although a common occurrence, yeast infection under breasts requires certain requisites which lead to the development of this scenario.

  • Women wearing very tight inners cause skin breakage and dermatitis

  • Women with large-sized breasts provide larger space for the fungi/bacteria to grow and expand.

  • Women who sweat uncontrollably

  • Women living in humid conditions


What Are The Symptoms?

A keen study was conducted in Sheffield over 300 women. Out of the total number almost 200 had lump feature, 42 had some sort of pain in the breast region, 29 of them had skin or a nipple problem and 31 had some sort of other symptoms. Around 180 women were detected with a form of yeast infection under breasts or around the breast region. Twenty-three were diagnosed with cancer, whereas the rest 99 of them were found with nothing as such. Surgeons detected that this infection could be treated by a GP. This study just goes to show how common this infection is in women and that yeast infection on the breast may occur due to a number of different reasons.

There are various ways in which your body will show signs of yeast infection under breast and not all women will face similar signs. However there are some common ways and they are:

  • Reddening of the skin and rashes

  • Discolouration of the skin

  • Peeling and cracking

  • Itchiness and a sense of feeling uncomfortable

  • Fluid discharge with very thin consistency


How To Get Rid Of the Yeast Infection?

  • One of the first things one must do is go and see a doctor. It is always better to not assume and diagnose on your own.
