Is the cervical cancer vaccine really effective? The cervical cancer vaccine cannot prevent cancer 100%

Cervical cancer is one of the common malignant tumors in women, and its incidence rate ranks second among gynecological tumors. According to incomplete statistics, there are 130,000 new cervical cancer patients in my country every year, and about 20,000 people die from cervical cancer every year. This disease is called "a killer endangering women's health". Can cervical cancer be prevented? What should I do if I find cervical precancerous lesions? Yesterday, Qian Jianhua, deputy director of Hangzhou Women's Hospital, reminded women over 21 years old to start cervical cancer screening. Cervical erosion will not develop into cervical cancer Qian Jianhua said that in recent years, the incidence of cervical cancer has a clear trend of getting younger, and the youngest outpatient is only in his early twenties. "In the outpatient clinic, I found that many women have misunderstandings about cervical cancer, thinking that the precursor of cervical cancer is cervical erosion, which then develops into cervical cancer. I also received a call from a patient saying that I had cervical cancer, but when I came for the examination, it was cervical erosion." Qian Jianhua said that in fact, the cause of cervical cancer is HPV virus infection, not caused by cervical erosion. Cervical erosion is one of the common phenomena in normal women of childbearing age and will not develop into cervical cancer. Qian Jianhua reminded that it is worth noting that the clinical manifestations of early cervical cancer are the same as those of cervical erosion in early lesions. Cervical cancer screening is required. Asymptomatic and non-infected cervical erosion does not necessarily require treatment. If there is more infection or secretion, medication or physical therapy should be given after examination. Overtreatment of cervical erosion can lead to miscarriage Qian Jianhua said that patients with cervical erosion should not be overtreated. Many young women have found cervical erosion in some private hospitals, and it is unnecessary to rush to use an ordinary knife (LEEP) to cut off the eroded part. "Killing a chicken with a butcher knife", this treatment method is only suitable for precancerous lesions. LEEP knife treatment has complications such as bleeding and infection. In addition, cervical insufficiency after LEEP knife treatment. "As we all know, the uterus is where the embryo grows and develops, and the cervix supports the fetus in the uterus. If a woman who has not given birth uses an ordinary knife to treat it, removing part of the cervix will cause the cervix to lose its supporting function, and she may have a miscarriage after pregnancy." Cervical cancer vaccine cannot prevent cancer 100% "Cervical cancer is the most common tumor of the reproductive system in women, and it is also the only malignant tumor with a clear cause." Qian Jianhua said that in a woman's lifetime, the probability of being infected with HPV is as high as 40% to 85%. But for most people, the virus will disappear within 9 to 15 months, and less than 1% of people will develop cervical cancer, so there is no need to panic too much. "Cervical cancer can be prevented by vaccination. At present, the cervical cancer vaccine has been launched overseas and will soon be introduced in China. But this does not mean that the cervical cancer vaccine can be completely prevented." Qian Jianhua said that in the past 10 years, HPV vaccine research has made progress, and many vaccines have completed I/II clinical trials, but there is still a distance from clinical application, such as clinical side effects and environmental safety. The strict species specificity of HPV virus makes it impossible to establish an animal model to evaluate the immune effect of the vaccine and the safety of the vaccine itself. In addition, how to choose the best vaccine strategy, such as optimizing the carrier, reasonably selecting the conditions for clinical application of the vaccine, etc. Therefore, it is necessary to develop an ideal HPV vaccine for treatment and large-scale promotion of the population will take time. In order to prevent cervical cancer, we should pay attention to regular screening and fixed partners, which is more meaningful. In addition, cervical cancer screening is very important. Women over 21 years old should start cervical cancer screening. Cytology screening can be performed every two years from 21 to 29 years old. Women over 30 years old need cytology screening and HPV testing at the same time. If two consecutive tests are normal, the screening interval can be appropriately extended to once every 3 years.
