Insufficient glandular tissue (IGT) is a rare condition that is seen in less than 2% of women. In these women, the breasts did not develop the necessary glandular tissues for breast milk creation. The breasts are tubular in shape (narrow and long instead of more rounded), have more than 4 cm flat space between the breasts, have a very large and bulbous areola, with no observable breast changes (such as tenderness or enlargement) during pregnancy.
