For the cervix those things, in fact, we women do not know much. The cervix is located in the lower part of the uterus, similar to a cone, 2.5-3.0cm long, the upper end is connected to the uterine body, and the lower end is deep into the vagina. 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. According to gynecologists, the five-year survival rate of cervical carcinoma in situ is 100%. The key is to early detection, early diagnosis, and early detection of cervical cancer and pre-cancerous lesions is completely possible. First, to prevent sexual promiscuity Human papillomavirus (HPV) infection is mainly transmitted through sexual transmission (other transmission is not excluded), so women should refuse multiple sexual partners, early start to have sex, repeated abortions and other behaviors, to remember that sexual promiscuity is always a very dangerous thing. Second, to view Cervicitis is not equivalent to HPV infection, not to mention precancerous lesions of cervical cancer. However, the incidence of cervical cancer in women with cervicitis is about ten times higher than in women without cervicitis. Therefore, when your doctor tells you that you have cervical erosion, it is best to be screened for cervical cancer and have a cervical cytology smear or TCT done. Early detection Women should be alert when they usually find themselves in the following situations: (1) contact bleeding (bleeding after intercourse); (2) pus discharge from the vagina; (3) irregular vaginal bleeding; (4) vaginal bleeding during pregnancy; (5) young women The presence of bloody vaginal discharge, all should go to the regular hospital for examination.
