Pap smears now called for every three years

It was in 1928 that scientists first discovered pap smears — a procedure in which a doctor can scrape cells from a woman’s cervix, look at them under a microscope and identify cancer, or the start of cancer. By the 1940s, pap smears were administered widely through the United States and Western world.
