| Breast masses or lumps are common while breastfeeding, especially in the first few weeks. It is usually a sign of engorgement, a plugged duct, or a breast abscess. Small cysts can sometimes fill with milk and usually appear just before a feeding and disappear after the feeding.
If you have a breast mass or lump that doesn't change in size and get smaller after a week or so, then you should see your doctor for a complete evaluation. Although breast masses during pregnancy are usually not from cancer, an ultrasound or mammography may be done to evaluate the mass. Other tests may include fine needle aspiration or surgical excision. You can usually continue breastfeeding during these tests.
