(HealthDayNews) -- Mastitis, an inflammation of breast tissue, can afflict women of any age. But it's most common in breast-feeding women, according to the U.S. Department of Agriculture's Children's Nutrition Research Center.
The condition usually occurs when germs enter the breast through a crack or abrasion in the nipple. The ensuing swelling and pain generally resolve once the inflammation clears.
If you're breast-feeding and experiencing repeated episodes of mastitis, it may be because something is blocking the flow of milk. This could be a cyst or perhaps a tumor. You should talk to your doctor as soon as possible.
