Pimples or bumps that merely look like pimples can appear anywhere on the body. However, they can be disconcerting when they are on the breast. With so much concern over breast cancer and other abnormalities, a pimple-like bump on or around the nipple could cause you to panic. Thankfully, most odd little bumps on the breast are nothing to be concerned about, though you should still see a physician if you are concerned.
Acne is one possible cause for pimple-like bumps on the breast. It can occur at any time of life, though it is most common during puberty and around menses in adult women, and anywhere on the body with hair follicles. If a hair follicle on your breast gets clogged with oil, dirt and dead skin cells, it will form a pimple, says AcneNet. While it is nothing to be concerned about, acne can scar if left untreated.
Another possible reason for pimple-like bumps on the breast is Montgomery glands. According to Breast Notes, these bumps don't grow and look like goosebumps on or around the nipple. These glands produce a lubricant to keep the nipple protected. They are most common in women older than 30.
In some cases, bumps that look like pimples might be a rash from a fungal infection, such as yeast, according to DermNet NZ. Since the breasts are an area that often gets sweaty and retains moisture, they're a breeding ground for yeast, which favor damp environments. A yeast infection would likely appear in the fold beneath the breasts as a red, itchy and inflamed rash.
Treatment for pimple-like bumps on the breast will depend on their cause. For acne, washing the area twice a day with a mild cleanser and applying an over-the-counter acne cream that contains benzoyl peroxide or salicylic acid should do the trick, according to AcneNet. Montgomery glands are normal and require no treatment. A yeast infection in the skin folds of the breast will require the application of a topical anti-fungal cream available over-the-counter or by prescription. Eating less sugar and supplementing with probiotics may also help cure the infection, according to DermNet NZ.
In some cases, a pimple-like bump on the breast can be a sign of a more serious condition like mastitis, cysts or fibroids, according to the Susan G. Komen Foundation. If the bump on your breast appears to be deeper than a mere surface lesion, consult with your doctor for an accurate diagnosis.
