A Food and Drug Administration (FDA) panel has recommended that a DNA test should be the primary screening tool for cervical cancer, rather than the traditional Pap smear. The DNA test detects the DNA of human papillomavirus (HPV), the sexually transmitted infection that causes almost all cases of cervical cancer.
“This is an important step forward for cervical cancer screening,” says Alexi Wright, MD, MPH, a medical oncologist in the Susan F. Smith Center for Women’s Cancers at Dana-Farber. Specifically, the DNA test screens for HPV-16 and HPV-18, the two highest-risk HPV strains, as well as 12 other high-risk HPV types, using a blood sample.
