Getting both the digene HPV Test and a Pap offers the most peace of mind for women 30 and older -- the age group that is most at risk of cervical cancer. If you do not have HPV and your Pap is normal, you can be confident you do not have abnormal cells that could develop into cervical cancer without being detected.
Women who are over 70 years who have never had a Pap smear, or those who request a Pap smear, of course could have a pap smear. Remember that, with the advent of HPV testing that goes along with the papsmear test, women over the age of 30 need only to have a pap with HPV every 3 years, if both of negative. woman over 30 years old, who has had normal pap smears and negative HPV tests, should continue to have pap smears every 5 years. She may stop having pap smears at age 65.
