Breasts in a woman go through a lot of physiological changes which may be cyclical or unusual. Most of these changes will not cause a concern but some breasts undergo changes which make a woman feel less confident or incomplete. Youthful breasts are composed of dense glandular tissue which is required for breast feeding. Post-breast feeding and as women age, the glandular tissue shrinks and is replaced by fat. By menopause, most women's breasts are completely soft and lost a lot of the volume as well as perkiness.
