Large, pendulous breasts may cause a woman to potentially experience various medical problems caused by the excessive weight of the breast tissue. Problems with posture, skeletal deformities, back and neck pain, skin irritations and breathing problems are common with this condition. Bra straps often leave indentations in the shoulder area. Many women, especially teenage girls, are very self-conscious if they have unusually large breasts. Breast reduction (reduction mammaplasty) removes fat, glandular tissue, and excessive skin, resulting in smaller, lighter and firmer breasts that are better-shaped in proportion to the rest of the body.
