@cashemire Good question. I do remember the questionnaire, ( it was the one recommended by the Today Show, I believe), linked benign breast tumors to a higher rate of breast cancer tumors. There is a link with multiple cysts according to NIH studies. NIH recently defunded, unfortunately. I just asked A.I. Google. It said: Research indicates that having multiple breast cysts ( especially at younger ages is associated with an increase of breast cancer because cysts may be a marker for generalized increased epithelial activity in the breast.
