The timing and frequency of cervical cancer screening depends on factors such as a woman’s age range and the presence of previous cervical-related lesions. Typically, women are recommended to be screened for cervical cancer starting at age 21. for women aged 21-29, cytology, or TCT, is recommended every three years. for women aged 30-65, TCT can continue every three years, or every five years in combination with high-risk HPV testing. For women with a history of cervical precancer and cervical cancer, annual cervical cancer screening is recommended. If the uterus and cervix have been removed and there is no history of cervical precancer or cervical cancer, screening for cervical cancer may not be performed. For women over 65 years of age, cervical cancer screening can be discontinued if three consecutive cervical cancer screenings have been normal and two consecutive HPV and TCT tests in the past 10 years have been negative. In addition, patients should refrain from having intercourse for more than three days and try to avoid menstruation before going to the hospital for gynecological examination before cervical cancer screening.
