What are the Histological Changes During Pregnancy and Lactation?
During pregnancy, breast tissue undergoes significant changes to prepare for lactation. The glands proliferate, ducts expand, and the amount of glandular tissue increases. During lactation, the alveoli become highly active in milk production, and the surrounding myoepithelial cells contract to aid in milk ejection. The glandular tissue is predominant, and the ducts are filled with milk.
