Have womens breasts become bigger over the last 100 years?

There is no scientific consensus on whether women's breasts have increased in size over the past 100 years. Various studies have examined this issue, with some reporting an increase in average breast size and others finding no significant change. Factors such as genetics, environmental influences, dietary changes, and hormonal contraception have been proposed as potential reasons for any observed increase in breast size. However, more research is needed to conclude definitively whether breasts have become significantly larger over this time period.
