Breast reduction is done when breasts appear too large in proportion to body frame, heavy, pendulous breasts having nipples and areolas pointed downward, one breast is much larger than the other, weight of breasts cause pain in back, neck or shoulder, size and weight of breasts restrict the physical activity and the largeness of breasts resulting in dissatisfaction or self-consciousness. Risks include bleeding, infection and reactions to anesthesia and following surgery it is possible that the breasts may not be perfectly symmetrical or the nipple height may vary slightly or permanent loss of sensation in the nipples or breasts may occur or in certain instances where incisions may have healed poorly repeat surgery may be needed. Breast size would remain fairly constant unless someone gain or lose a significant amount of weight or become pregnant. However natural factors like gravity and aging will eventually affect the size and shape of virtually every woman?s breasts.
