=F dFLrx~l Most American women know regular Pap smears cut the risk of cervical cancer, but that doesn’t mean they go in to get the test. Half the women who develop the disease haven’t had a Pap test for three years. But a new test may one day offer a user—friendlier alternative. Two studies in last week’s Journal of the American Medical Association report that a DNA test detects cervical cancer just as well as Pap smears do. Better yet, women can collect samples for the test themselves. The Pap smear has caused a fivefold drop in cervical cancer since 1960s. But since a doctor must take the smear during a pelvic exam, women who don’t have access to gynecologists aren’t screened. So a self-collected test could be good news for patients, like the 1,365 South Africans in one of the JAMA studies. They collected their own vaginal samples on swabs. Samples were sent to the United States, where a DNA test caught 66 percent of the women’s cervical cancers; 68 percent were detected by Pap smears. And when doctors collected the samples, that study, and a second one of Costa Rican women, found that DNA tests actually caught more cancers than Pap smears.
