Breast Aplasia (Amastia)

Breast Aplasia (Amastia)

Dr. Kennedy
Breast aplasia is a rare condition wherein the normal
growth of the breast or nipple never takes place. They are congenitally absent.
There is no sign whatsoever of the breast tissue, areola or nipple. Absence
of the breast (also called, amastia) is frequently not alone as the only
problem. Unilateral amastia (amastia just on one side) is often associated
with absence of the pectoral muscles (the muscles of the front of the chest).
Bilateral amastia (with absence of both breasts) is associated in 40%
of cases with multiple congenital anomalies (birth defects) involving other
parts of the body as well. Amastia is thought to be described in the Bible:
“We have a little sister, and she hath no breasts” (Song of Solomon
VIII:8). Amastia can be distinguished from amazia — wherein breast tissue is
absent, but the nipple is present — a condition that typically is a result
of radiation or surgery.
