Breastfeeding women are usually not tested. However, an exam is often helpful to confirm the diagnosis and rule out complications such as an abscess.
Sometimes for infections that keep returning, milk from the nipple will be cultured. In women who are not breastfeeding, testing may include mammography or breast biopsy.
Self-care may include applying moist heat to the infected breast tissue for 15 to 20 minutes four times a day.
Antibiotic medications are usually very effective in treating a breast infection. You are encouraged to continue to breastfeed or to pump to relieve breast engorgement from milk production while receiving treatment.
The condition usually clears quickly with antibiotic therapy.
In severe infections, an abscess may develop. Abscesses need to be drained, either as an office procedure or with surgery. Women with abscesses may be told to temporarily stop breastfeeding.
Calling your health care provider
Call your health care provider if:
Any portion of the breast tissue becomes reddened, tender, swollen, or hot
You are breastfeeding and develop a high fever
The lymph nodes in the armpit become tender or swollen
The following may help reduce the risk of breast infections:
Careful nipple care to prevent irritation and cracking
Feeding often and pumping milk to prevent engorgement of the breast
Proper breastfeeding technique with good latching by the baby
Weaning slowly, over several weeks, rather than abruptly stopping breastfeeding
