Inflammatory condition of the breast

Breast infections are usually caused by a common bacteria found on normal skin (Staphylococcus aureus). The bacteria enter through a break or crack in the skin, usually the nipple. The infection then takes place in the parenchymal (fatty) tissue and causes swelling of the parenchymal tissue outside the milk ducts. This swelling in turn compresses on the milk ducts. The result is pain and swelling of the infected breast. Breast infections usually occur in women who are breastfeeding. Breast infections that are not related to breastfeeding must be differentiated from a rare form of breast cancer.

Mastitis

Mastitis is an infection of the breast. It is usually caused by a Streptococcus or Staphylococcus (Strep or Staph) bacteria and can be very painful. If untreated serious illness can result. It usually occurs two to four weeks after delivery and results from bacteria introduced by the baby into cracks or fissures in the nipple or areola. These bacteria then multiply causing your body to mount an inflammatory response. The inflammatory response is what alerts you to the infection and is your body's way of fighting the invading bacteria. This immune response produces a painful red and hard surface on the breast that is tender to touch. Fever often sets in and may be accompanied by chills and sweats. Despite your body's best efforts to fight the infection, antibiotics are recommended.
