Cervical cancer is caused by persistent infection of high-risk human papillomavirus, and the most important way of transmission of this virus is sexual contact, so there is a close relationship between cervical cancer and sexual life. Risk factors of cervical cancer include early sexual debut, multiple sexual partners, unclean sex, etc. At present, cervical cancer can be prevented through HPV vaccination and early screening of cervical cancer. It is suggested that patients should pay attention to the safety and hygiene of sexual life, and can receive HPV vaccine at an appropriate age. The vaccine cannot prevent 100% of the occurrence of cervical cancer, so regular cervical cancer screening is very necessary. When patients have uncomfortable symptoms, they should seek medical treatment in time and under the guidance of professional doctors.
