is there an increase in breast cancer?
Fact 1: Breast Cancer Is Much More Common During this period—1970 to 2014—the U.S. population increased 56.8 percent (203,392,031 to 318,892,100). Thus, the rate of increase in female breast cancer has been more than 4-fold (i.e., 4.26-fold) the increase in the U.S. population during the same period.
