Specifically, the guidelines recommend that women should not be screened for cervical cancer with the Pap test until they are 21 years old. Between 21 and 29 they should have a Pap test only once every three years, instead of every year. Between 30 and 65, women should either have a Pap test every three years, OR a Pap test every five years if it is combined with a test for HPV. Women over 65 need not be screened at all, provided they are healthy.
The American Cancer Society agrees with the new recommendations, and has already incorporated them into their cancer screening guidelines posted on their website.
