The prevention of cervical cancer is primary, secondary and tertiary prevention. Primary prevention is behavioral prevention and vaccine prevention. The main cause of cervical cancer is HPV infection, which is a virus transmitted mainly through sexual intercourse, and persistent infection with HPV high-risk subtypes is a definite cause of cervical cancer. What are the primary prevention measures for cervical cancer? Both husband and wife should be clean, not to have such sexually transmitted diseases and not to have mutual infection of HPV virus, which is the primary prevention from this aspect. At the same time, women can also be vaccinated against cervical cancer to produce sufficient antibodies to prevent new HPV infections at this time. There is also secondary prevention for cervical cancer, which is early detection and early treatment. Early detection is mainly TCT screening and HPV screening for cervical cancer. Tertiary prevention of cervical cancer is early treatment, which is timely surgical treatment or radiation treatment. To sum up, the main measures for primary prevention of cervical cancer are for both spouses to be clean, not to have multiple sexual partners, and not to get infected with HPV virus. Women can get the bivalent, quadrivalent or nine-valent cervical cancer vaccine at an appropriate age.
