Red lump on my friends breast? Breastfeeding. So do I stop?

Painful breastfeed. When your baby is not able to empty the milk in the sinuses and ducts of the breast, the milk collection will cause distention of the breast in the form of lumps. Stopping to breastfeed will even cause infection. Emptying the retained milk by teaching the baby to correctly latch and manual or electrical pumping will relieve the situation. The baby will not be harmed by the infected milk.
