Frequency depends on a few factors, including your age and medical history. If you’re not sure whether you need the procedure, speak to your doctor.
As a general rule, screenings begin at age 21. Women with normal screening results retest every three years until they reach 30; those with an abnormal result may require more frequent exams.
After age 30, screening may be reduced to every three to five years, depending on the patient’s history. HPV testing also typically begins at age 30. Women over 30 who have tested positive for HPV typically undergo yearly Pap smear screening, as this group is at higher risk for cervical cancer.
