| The breast is a dynamic organ responding to hormone, age, and other factors. As an aging process,fibroglandular tissue of the breast parenchyma shows progressive fatty replacement. To evaluate the normal agingprocess, we reviewed ultrasonomammograms of 220 persons who had normal breast with contralateral benign diseaseretrospectively. Twenty persons in second decade and 40 persons for each decade from third to seventh werestudied. Skin thickness, ductal prominency, and echoes of mammary layer did not changed to age. Fatty change ofmammary layer became prominent after fourth decade and then revealed more than 70% after sixth decade. Thicknessof mammary layer decreased after second decade. The posterior portion of Cooper's ligament arising fromprepectoral fascia began to appear after fourth decade and was prominent after sixth decade. In conclusion,involutional change of the breast begins in premenopausal period. |
