Can hormonal contraceptives lead to breast tissue growth?

Yes, it may happen, although the extent to which breast size increases depends on the woman and the birth control method used. Estrogen and progestin can cause you to experience an increase in breast size, but it generally reverses after a few cycles or when the woman stops using them. This side effect is often accompanied by breast tenderness (i.e. mastalgia).
