Cervical cancer is one of the three major malignant tumors of the female reproductive system, and its most common type is squamous cell carcinoma, which is causally related to HPV infection, but it does not mean that HPV positivity necessarily leads to cervical cancer. The high incidence age of in situ cancer is 30 to 35 years old, and in recent years its incidence has a tendency to be younger. Early detection and treatment of cervical cancer and precancerous lesions have been made possible by the widespread use of cervical cytology screening in the last 40 years. The incidence and mortality rate of cervical cancer have been significantly reduced. I wonder how much you women know about the cervix. The cervix is located in the lower part of the uterus, connected to the uterine body at the upper end and deep into the vagina at the lower end. The cervix is an important line of defense to prevent pathogenic microorganisms from entering the uterus, fallopian tubes and ovaries, and this line of defense is particularly vulnerable to various pathogenic bacteria. The five-year survival rate of cervical cancer in situ is 100%. The key is early detection and early diagnosis, and early detection of cervical cancer and precancerous lesions is completely achievable. I: HPV vaccination (preventive vaccine) Need to be vaccinated before the first sexual intercourse is the most effective, once there is sexual intercourse there may be high-risk HPV infection. Two: Pay attention to sexual hygiene Human papillomavirus (HPV) infection is mainly transmitted through sex, (can also be transmitted in other ways), so women should refuse multiple sexual partners, start having sex too early, repeated abortions and other behaviors, to remember that a bad sex life is a very dangerous thing. Third, regular checkups Cervicitis is not equivalent to HPV infection, let alone precancerous lesions of cervical cancer. However, the incidence of cervical cancer in women with cervicitis is about ten times higher than that in women without cervicitis. Therefore, when your doctor tells you that you have cervical erosion, it is better to have a screening test for cervical cancer by having a cervical cytology smear or TCT. IV. Early detection Women should be alert when they usually find themselves in the following situations: (1) having contact bleeding (bleeding after intercourse); (2) having purulent vaginal discharge; (3) having irregular vaginal bleeding; (4) having vaginal bleeding during pregnancy; (5) young women The presence of a bloody vaginal discharge. To prevent even a 1% chance of this from happening to you, you need to see your doctor regularly for screening. You can start with a cervical exfoliation cytology test such as TCT or LCT combined with HPV, a colposcopy in the second step, and then a histopathological analysis of the cervix in the third step if there is a problem.
