A new study shows a woman's DNA may predict her risk of cervical cancer better than a repeat pap smear.

Women who have an abnormal pap smear are typically called back for a repeat test to see if cells are clearly or mildly irregular. But researchers at the Scientific Institute of Public Health found that a DNA based test more accurately identified women with pre-cancer than a repeat smear.

They admit the test does result in more false positives and say more specific tests may be needed for those with mildly abnormal cells.
