<unk> or sagging of the female breast is a natural consequence of aging. The rate at which a woman's breasts drop and the degree of<unk> depends on many factors. The key factors influencing breast<unk> over a woman's lifetime are cigarette smoking, her number of pregnancies, higher body mass index, larger bra cup size, and significant weight change. Post-menopausal women or people with collagen deficiencies (such as Ehlers-Danlos) may experience increased<unk> due to a loss of skin elasticity. Many women and medical professionals mistakenly believe that breastfeeding increases sagging. It is also commonly believed that the breast itself offers insufficient support and that wearing a bra prevents sagging, which has not been found to be true. Plastic surgeons categorize the degree of<unk> by evaluating the position of the nipple relative to the infra-mammary fold, the point at which the underside of the breasts attach to the chest wall. In the most advanced stage, the nipples are below the fold and point toward the ground.
