"What is breast hypoplasia and what are the causes?
Breast hypoplasia is the technical term referring to underdevelopment of the breast. We also often refer to this as "insufficient mammary tissue", because it is the inadequate development of the glandular tissue that is a problem more than mere size. Hypoplastic breasts
can vary in cup size but often have an "empty sac" look to them, rather than the normal filling out of the breast. It is not unusual to see one breast markedly larger than the other, more than the usual small asymmetry."
