Today, a mother-to-be who is pregnant came in for a consultation and asked if she should be screened for cervical cancer during her pregnancy. Will cervical cancer screening lead to miscarriage at this time? So far, the detection of precancerous lesions and early stage cancer through screening is still the key to cervical cancer prevention and treatment in China. Early detection through screening can fully achieve early diagnosis and treatment. There is no difference in the progression of cervical cancer during pregnancy and non-pregnancy, but early diagnosis may sometimes be delayed because vaginal manipulation is contraindicated during pregnancy. Cervical screening should be done once during early pregnancy, and if there is no screening in the year before pregnancy, a screening should be done in early pregnancy. If it is only precancerous, the pregnancy can be continued until the baby is born and then operated.
