    Breast infections are usually caused by bacteria. Rarely, breast infections lead to a breast abscess (a collection of pus in the breast).

    Mastitis refers to painful inflammation of the breast, which is usually accompanied by a breast infection and most commonly occurs in breastfeeding women.

    (See also Overview of Breast Disorders.)

    Breast abscesses are less common than breast infections. An abscess may develop if a breast infection is not treated.

    Doctors usually drain (aspirate) an abscess with a needle. Ultrasonography is used to guide placement of the needle. Sometimes doctors need to make an incision to drain the abscess.

    Usually, women are also treated with antibiotics.
