With mastitis, a woman often feels a hard, sore spot inside the breast; it can occur as a result of a blocked milk duct or bacteria entering the breast through a break in the skin.
Mastitis, also known as lactation mastitis, is thought to affect approximately 10 percent of all breast-feeding mothers. However, study results vary significantly, from a very small percentage of cases up to 33 percent.
The condition tends to emerge during the first 3 months after giving birth, but it can occur up to 2 years later.
Some mothers mistakenly wean their babies when they develop mastitis. In most cases, breast-feeding can continue during mastitis. In the vast majority of cases, only one breast is affected.
Sometimes, mastitis can affect women who are not lactating, but it is uncommon. In very rare cases, it can affect men.Contents of this article:
