Before taking the cervical cancer vaccine, you need to undergo cervical cancer screening, HPV test, coagulation pentameter test, pregnancy test, etc. It is safer to be vaccinated under the guidance of a professional physician. Cervical cancer is a malignant tumor originating from the cervix, and the main cause of its development is the persistent infection of high-risk human papillomavirus (HPV). Therefore, the cervical cancer vaccine, also known as the HPV vaccine, is available on the market, which can prevent cervical cancer by preventing the infection of human papillomavirus. Before receiving the cervical cancer vaccine, cervical cancer screening should be carried out first, which can clarify whether malignant lesions already exist in the cervix and whether vaccination is necessary; in addition, it can also clarify whether there is human papillomavirus (HPV) infection in the cervix, which, if it already exists, can lead to a decrease in the protective power of the vaccine. In addition, for patients with abnormal coagulation function, vaccination may lead to local bleeding, it is recommended to be cautious of vaccination, and patients should improve the coagulation quintuple check before vaccination. The safety of cervical cancer vaccine for women during early pregnancy is not clear, and the vaccination may lead to fetal malformations, so pregnant women should not be vaccinated, and a pregnancy test should be conducted before vaccination to rule out pregnancy and other contraindications to vaccination. Since there are many contraindications to vaccination, patients should be vaccinated under the guidance of a professional physician to avoid adverse consequences.
