How will a previous abscess affect my milk supply?
Most breastfeeding mothers who have had a breast abscess with a previous baby will have a normal milk supply on the affected side. If it is not normal, the other breast may compensate and produce more milk. A decreased supply is more likely if the abscess was large, persistent, immediately behind the nipple, or if the abscess was treated by cutting into the breast to release the pus. The abscess or the cut can damage milk glands and ducts. Having a breast abscess as a baby girl can affect breast development and later milk production.
