I'm not arguing that they don't, but the fact is

- the American Cancer Society didn't start promoting cervical cancer screening until the 1960s [1] - mammography was first recommended officialy in 1976 [1]

Screening was just coming of age 50 years ago so it's no surprise we started to find something once we started looking for it.
