Cervical screening, if there are no high-risk factors, is usually done once every three years, but if there are high-risk factors, it is recommended to check once every three to six months. Cervical screening enables early detection of cervical cancer. Cervical cancer has a relatively high possibility of cure through early detection and early treatment. For patients who do not have high risk factors such as human papillomavirus infection, cervical cancer screening once every three years is usually sufficient. However, for patients who have already been detected with high risk factors in previous examinations, then it is recommended to be examined once every 3~6 months to closely observe the trend of the disease. When performing cervical screening, you need to be careful to avoid menstruation, and it is best to perform cervical screening 3 days after menstruation has ended. Once HPV infection and other abnormalities appear in the screening test, it is recommended to consult a doctor in a timely manner to improve the relevant examinations and standardize the treatment.
