Breast Infection and Abscess

A breast infection (mastitis) is rare, except around the time of childbirth (see Section 22, Chapter 262) or after an injury or surgery. The most common symptom is a swollen, red area that feels warm and tender. An uncommon type of breast cancer called inflammatory breast cancer (see Section 22, Chapter 251) can produce similar symptoms. A breast infection is treated with antibiotics.

A breast abscess, which is even rarer, is a collection of pus in the breast. An abscess may develop if a breast infection is not treated. An abscess is treated with antibiotics and is usually drained surgically.
