Denise, It is still possible that this mom has glandular hypoplasia, she has all the classic signs except the tubular shape. She might just have been good at putting down the fatty tissue stroma, without developing the milk glands. It bothers me that she was given a reduction in the bigger breast as a teen, didn't someone stop to think they might be destroying her one functional breast? Here docs are far more likely to offer an implant for the smaller breast. Catherine Watson Genna, IBCLC
