What is mastitis?

Also known as: Breast infection, lactation mastitis

Mastitis is an inflammation of the breast, which may, or may not be related to an infection. It most commonly occurs in breastfeeding mothers one to three months after the delivery of the baby (during the first 6 months of breastfeeding or anytime).

(Mastitis in infants under 2 months of age is a separate discussion).
