N64.2: Atrophy of breast

The breast is made up of fatty tissue, connective tissue and the mammary gland. Milk is produced in the mammary gland during and after pregnancy so that the child can be fed.

There are various reasons why breasts shrink. You may have too many male sex hormones or not enough female sex hormones in your body. This can lead to changes in the breast.
