Dear ladies and gentlemen who are concerned about ladies’ health: I would like to introduce cervical cancer to you. It is known that cervical cancer is one of the three major malignant tumors in gynecology and one of the easiest gynecological tumors to detect at an early stage. As long as people give attention to it, it will not lead to adverse consequences. The cause of cervical cancer is clearly HPV, which most people know because the discoverer won the Nobel Prize in Medicine. However, not all HPV-infected patients must suffer from cervical cancer because it has many subtypes, and only high-risk subtypes are prone to cancer; nor does HPV infection cause cancer overnight, but it needs a process, latent, role, developmental stage, and gradual evolution in the cervical area, generally about 5-15 years. Therefore, cervical cancer is preventable and early blocked. Zhang Weiyang, Department of Obstetrics and Gynecology, Second Hospital of Jilin University HPV infection is mainly through the sexual transmission route, early sexual behavior <16 years old, sexual disorders, including sexual partners. This requires one to be clean and the couple to cherish each other to avoid HPV infection. HPV infection requires an evolutionary process to cause cancer, and during this period, it has to undergo precancerous lesions, which is often referred to as CIN, so the significance of regular screening is highlighted. If CIN is treated early, the progression to cancer can be stopped. If TCT is normal and HPV infection is present, then antiviral treatment can be given, such as localized Sinorelin; if TCT is abnormal, colposcopy biopsy for pathology can be done if necessary to detect CIN and treat it as early as possible to stop it before cancer.
