The areolar of a patient with enlarged breast glands or excess fat can be large due to the increase in tissue volume. In most cases, removal of the fat and gland, will lead to the overlying skin retracting and also the areolar getting smaller.
However in certain cases, if there is a lot of excessive skin, there may be a need to cut away the excess skin. This is usually only needed in severe cases where patients have undergone massive weight loss.
