Amazia

Amazia refers to a condition where breast tissue is absent, either congenitally or iatrogenically (the nipple and aureola remain present). The condition is typically the result of surgical removal or radiation therapy. Amazia in girls can be treated with augmentation mammoplasty.

Amazia differs from amastia (the complete absence of breast tissue, nipple, and aureola), although the two conditions are often (erroneously) thought to be identical. The terms "amazia" and "amastia" are thus often used interchangeably, even though the two conditions are medically different.
