But this gap of many decades between environmental exposures at younger ages and the older ages at which most breast cancers are diagnosed makes research difficult. It can be hard for older women to remember what happened to them when they were much younger or for researchers to follow a large enough group of girls until they reach the older ages at which some of them develop breast cancer.
