Increasing the size of a woman’s breasts isn’t the sole reason for undertaking breast surgery Many women find their breast size to be uncomfortably large. This can cause physical and emotional distress and is easily remedied. Breast reduction surgery reduces the size of breasts by removing fat and breast tissue. In addition to making your breasts smaller, your plastic surgeon will often also reshape your breasts to create a more esthetically pleasing shape and size. Depending on the desired outcome for your procedure, your cosmetic surgeon might recommend the reduction be accompanied by a breast lift. The result would be a reduced size and completely different shape. The surgery is also often performed as part of a mommy makeover.
