The cervix, as the name suggests, is the junction of the uterus and the vagina, just like the neck of the uterus, which is one of the important organ tissues of female reproduction and reproduction.
The cervix is very delicate and fragile, it is not only vulnerable to various pathogens, but also a female reproductive site prone to cancer.
Because of this, cervical cancer is the most high-incidence reproductive tract malignancy in mainland women, and the number of newly diagnosed cervical cancer patients reaches 135,000 every year, of which 80,000 people die.
In the past 20 years, the incidence of cervical cancer has shown a significant trend of rejuvenation, and more and more women have begun to pay attention to cervical health and pay attention to cancer screening.
The HPV vaccine is one of the few means to prevent cervical cancer
99.7% of cervical cancer is caused by HPV infection, and the HPV vaccine can prevent cervical cancer caused by HPV virus infection, which is the world's vaccine with cancer prevention effect.
Recently, the website of the Hainan Provincial Government published the "Practical Matters for the Private Sector in 2022 by the Provincial Party Committee and the Provincial Government", one of which includes the provision of domestic 2-valent HPV vaccines for school-age girls free of charge.
According to the document report, Hainan Province will provide domestic 2-valent HPV vaccines for women of appropriate age who are 13-14 years old and a half years old and have no history of HPV vaccination, and implement vaccination in accordance with the principle of "informed consent and voluntary free", and it is expected that provincial financial funds of 49.842 million yuan will be required in 2022.
At present, the free HPV vaccination work will start from the beginning of the Spring Festival and is being carried out in a planned and step-by-step manner in the province.
Cervical cancer, which populations are at high risk?
According to the current clinical data, cervical cancer is the only malignant tumor with a clear etiology, and its incidence is directly related to the continuous infection of high-risk hpillomavirus in women.
According to this main cause, and its transmission route, it is possible to understand the main high-risk groups of cervical cancer.
Usually, the following groups of people have a relatively high incidence of cervical cancer:
1. Sexual life disorders
The study found that the peak period of HPV infection is around 20-30 years old, this age stage of HPV infection.
Nearly 25 to 30% of them are high-risk HPV infections, and then the infection rate gradually decreases as they age. And the reason for this is directly related to sex.
Because the virus is mainly transmitted through sexual channels, if a woman has multiple sexual partners, or a male partner has multiple sexual partners, it will increase the risk of infection.
2, sex life is too early
I have to say that the concept of sex in the mainland in recent years is indeed very open, but after all, it is affected by the shackles of traditional thought, and the popularization of continental sexual knowledge is obviously insufficient, and many girls do not know how to protect themselves although they are exposed to sex.
If a girl has sex before the age of 16, marrying and giving birth too early, miscarrying at too young age, etc., it will increase her chances of cervical cancer.
At this time, because the cervical tissue is not fully mature, it is susceptible to damage, induces chronic cervicitis, and the risk of HPV infection is also higher.
3. Fertility
In addition to having children prematurely, if a woman has multiple births, multiple miscarriages, etc. in her lifetime, this will also increase the chance of cancer.
Because the position of the cervix is very special, whether it is curettage surgery or vaginal delivery, there may be different degrees of cervical damage, and the probability of infection with various pathogens is relatively large.
4. Long-term smoking
Cigarettes contain a variety of carcinogens, including polycyclic aromatic hydrocarbon compounds, nitrosamines and the like.
At the same time, the inhalation of nicotine will also reduce immune function, resulting in HPV virus infection, which cannot be recognized and cleared by the immune system in time, which in turn increases the risk of future cancer.
In addition to the above factors, there are also studies that have found that the emergence of cervical cancer has a certain genetic predisposition, that is, if someone in the immediate family has cervical cancer, then they are also a high-risk group of cervical cancer.
For the above types of high-risk groups, it is necessary to improve vigilance against cervical cancer, conduct regular anti-cancer screening, and meet the conditions to inject HPV vaccines.
