Hello Anonymous,
Premenstrual swelling and tenderness of both breasts occurs during the second half of the menstrual cycle.
More estrogen is made early in the cycle and it peaks just before mid-cycle. This causes enlargement of the breast ducts.
In a 28 day cycle, the amount of progesterone peaks near the 21st day.This causes growth of the milk glands.
