It is not allowed to insert pills on the night of cervical cancer screening. Because cervical cancer screening is an examination of cervical exfoliated cells, which uses soft brushes to remove the epithelial cells of the cervix, which may irritate the mucous membrane of the cervix, and in some cases, may cause a small amount of bleeding, so it is not allowed to insert pills in the evening of the same day of the cervical cancer screening. It is also forbidden to have sexual intercourse and take basin bath to avoid the upward infection of inflammation. Cervical cancer screening is a necessary test for women to screen for cervical diseases, mainly TCT and HPV. TCT is a liquid-based cytology test to find out whether there are atypical squamous epithelial cells or cancer cells from the cellular aspect, and HPV is a screening test for human papillomavirus (HPV) of the cervix, which is a high-risk type of HPV infection, and if there is any persistent HPV infection, it will cause pre-cancerous changes of the cervix, or even cervical cancer, so TCT and HPV are the most important tests. So TCT and HPV are two very important tests.
