Over 30, Out of Luck

Premium

Less than a month after it issued a warning on the usefulness of PSA screening for prostate cancer, a US government advisory panel says HPV screening may not be very accurate for detecting cervical cancer in women older than 30, reports Bloomberg's Adriel Bettelheim. A draft report from the US Preventive Services Task Force says more evidence is needed to declare HPV screening — usually done by a gynecologist as a test of the cells near the cervix for evidence of the virus — a useful tool for this particular age group, Bettelheim says. The panel will accept public comments on this recommendation until November 16.
