CHANGES IN THE BREAST - PREGNANCY

Starting in the second month the breast enlarge progressively and become somewhat nodular as both glands and ducts increase. The nipples enlarge and become darker and more erectile. Later the areolae also darken and the visible veins over the breast become accentuated. Colostrum, a thick, yellowish fluid, can often be expressed from the nipple by gentle massage during the later part of pregnancy.

CHANGES IN THE BREAST - ELDERLY

The breasts of an aging woman tend to diminish in size as glandular tissue atrophies and is replaced by fat. Although the proportion of fat increases, its total amount may also decrease. The breasts often get flabby and hang lower on the chest. The ducts surrounding the nipple may become more easily palpable as firm strands.
