Breast implant
Since the late nineteenth century, breast implants have been used to surgically augment the size (volume), modify the shape (contour), and enhance the feel (tact) of a woman's breasts. In 1895, surgeon Vincenz Czerny effected the earliest breast implant emplacement when he used the patient's autologous adipose tissue, harvested from a benign lumbar lipoma, to repair the asymmetry of the breast from which he had removed a tumor. In 1889, surgeon Robert Gersuny experimented with paraffin injections, with disastrous results.
Nursing bra
A woman's breasts grow during pregnancy, usually 1 to 2 cup sizes, and potentially several cup sizes. A woman who wore a C-cup bra prior to her pregnancy may need to buy a larger bra while nursing. Once the baby is born and about 50 to 73 hours after birth, the mother will experience her breasts filling with milk (sometimes referred to as “milk coming in”) and at that point changes in the breast happen very quickly. Once lactation begins, the woman's breasts swell significantly and can feel achy, lumpy and heavy (which is referred to as engorgement).
