Recently there are a lot of cervical cancer vaccine inoculation (HPV vaccine) inquiry and discussion, because at present many women can not be vaccinated, said to go to Hongkong to HPV vaccination, everyone for health care! But to remind you that the inoculation of cervical cancer vaccine does not mean the 100% prevention of cervical cancer, because the vaccine failed to all oncogenic virus subtypes in the world, always the most effective means of prevention of cervical cancer, cervical cancer screening regularly!
Cervical cancer is one of malignant tumors in women, the world has more than 50 new cases each year, of which about 1/3 from Chinese. In Chinese, cervical cancer incidence and mortality are very high, there are reports that China mortality from 3/10 million to 20/10 million a year, per 1000 women in 4 were found to have cervical cancer per 10 thousand women in 2 people died of cervical cancer. In 2003 the famous artist Anita Mui die of the disease.
The relationship between HPV virus and cervical cancer?
About 10 various types of HPV can make the cervical carcinogenesis, and statistics of Union Medical College Institute of cancer research shows that 14.2% rate in our country female infection (7 China women in 1 people infected with high-risk HPV!). The high risk of HPV in the HPV16 and HPV18 two viruses cause about 70% of cervical cancer cases around the world, and this proportion is higher in China, about 86%. Of course, some people infected with the HPV virus can not be a lifetime of cervical cancer, so the two can not be equated with.
How does HPV infect?
HPV infection is the most important way of sexual life, but not only through sexual life, close contact can lead to women infected with HPV, so women's life is the opportunity to have HPV infection.
Cervical cancer vaccine the most appropriate age and population?
Because the HPV vaccine to prevent HPV infection, but not in treatment, so the risk of infection before (i.e. before the one-time try) HPV vaccine is to get the best protection, WHO (WHO) pointed out that the most appropriate HPV with HPV for 11-12 years of age, can obtain the HPV vaccine to protect people from 9-26 years old. Men also suffer from HPV infection of condyloma acuminatum, penile cancer, anal cancer and other diseases, although the probability is low, but the infected male can spread HPV to their sexual partners, so vaccination for men, is meaningful, so that the HPV vaccine is beneficial to people's health.
At present, there are several kinds of cervical cancer vaccine?
So far there have been two kinds of cervical cancer prevention vaccine for HPV, a Merck in the United States in 2006 approved the added Wei Miao (English Name: Gardasil) or Gady (Gardisil or Silgard), is the 4 valent vaccine can prevent caused by HPV6, 11, 16, 18 of cervical cancer and vaginal cancer, anal cancer, condyloma and other diseases; the other is GlaxoSmithKline's production of "Yan Hui Kang", is Cervarix™ 2 valent vaccine to prevent HPV-16 and HPV-18 these two kinds of more than 70% caused by cervical cancer culprit. Although cervical cancer vaccine has been listed more than and 160 countries in the world (China's Hongkong and Taiwan have also been promoted), but has yet to complete clinical trials in Chinese, and China, Xiamen University developed cervical cancer vaccine, has completed the one or two phase, is currently doing phase three clinical trials.
If you have a cervical cancer vaccine, you won't get cervical cancer?
The cervical cancer vaccine inoculation, does not mean the 100% prevention of cervical cancer, because the vaccine failed to all carcinogenic virus subtype (12 high-risk subtypes, the vaccine only for 2 of them), so the screening of cervical cancer and cervical cancer vaccine is not a substitute for regular should do!
Cervical cancer is how to produce factors that lead to cervical cancer complicated with DNA gene or HPV virus and other various reasons, but the formation of cervical cancer is a cycle, this cycle is about 5-10 years, usually every once related screening for 1 years, during this period of time as long as the examination to determine cancer signs of immediate surgery can be cured.
Screening is mainly CIN lesions: can be divided into CIN1, CIN2, CIN3 three, CIN3 is one of the biggest disease risk of cervical cancer, if the relevant index increased gradually to take measures of treatment, this is a dynamic and occasional high drop back to normal is no risk.
Cervical cancer three line of defense:
The first line of Defense: the injection of HPV vaccine, mainly for people aged 9-26 years of asexual life of women
The second line of Defense: women aged 21 years or over 3 years of sexual life of women, at least every two years TCT cervical screening (even if the HPV vaccine is to do), if the above examination showed HPV positive, then you can do colposcopy, take a little on the cervical tissue, the pathological examination, to determine whether in precancerous lesions;
The third line of Defense: the precancerous lesions in severe (CIN2, 3), should do surgery, namely cervical conization, to determine whether the more severe cervical carcinoma in situ, early invasive cervical cancer, cervical carcinoma, so that the doctor reasonable treatment. It can be said that if such regular cancer screening, early blocking cervical cancer development.
So doctors remind: in the international community has always been the most effective means of prevention of cervical cancer - regular screening of cervical cancer!
