MastitisMastitis is an infection of the breast tissue caused by bacteria or a blocked milk duct. You may have symptoms such as:
- breast tenderness
- skin redness
- skin warmth
Breast abscessesIf mastitis isn’t treated, a painful abscess containing pus can develop. This mass might appear as a swollen lump that’s red and hot.
FibroadenomasFibroadenomas are benign (noncancerous) tumors that can develop in the breast. They may feel like marbles when you touch them. They usually move under the skin and aren’t tender.
GalactocelesThese harmless milk-filled cysts are typically painless. In general, noncancerous lumps feel smooth and round and move within the breast. Cancerous lumps are usually hard and irregular in shape and they don’t move.

- doesn’t go away after about a week
- comes back in the same place after treatment for a blocked duct
- keeps growing

Surgery and breastfeedingYou may be able to continue breastfeeding before and after having surgery to remove your tumor depending on the type of procedure. Talk to your doctor about whether it’s safe for you and your baby to continue breastfeeding. If you have a double mastectomy, you won’t be able to breastfeed. Treating a breast with radiation after a lumpectomy means it usually produces little or no milk. You may be able to breastfeed with the untreated breast, however. Ask your doctor what medications you’ll receive before and after surgery and if they’re safe for a baby who’s breastfed. You might need to pump your milk and discard it for a period of time before resuming breastfeeding.
Chemotherapy and breastfeedingIf you need chemotherapy, you’ll have to stop breastfeeding your baby. The powerful drugs used in chemotherapy can affect how cells divide in the body.
Radiation therapy and breastfeedingYou might be able to continue breastfeeding while receiving radiation therapy. It depends on the type of radiation you have. Some women can breastfeed with the unaffected breast only.
Treatment side effectsIt’s important to remember that you could experience side effects from treatment. These might include:
- weight loss
