The relationship between HPV and cervical cancer unravels the palace mystery
Cervical cancer is the fourth most common cancer among women worldwide, according to who data. It is estimated that there were about 570,000 new cases of cervical cancer worldwide in 2018, and about 311,000 women died of cervical cancer. Around the world, cervical cancer causes one new patient every minute, and one woman dies of it every two minutes.
Cervical cancer is one of the most common gynecological malignancies, second only to breast cancer, accounting for the second highest incidence of malignant tumors in China. That is, cervical cancer has become the "second killer" of women's health.
Therefore, it is necessary to strengthen health awareness and prevent cervical cancer in advance.
So how does cervical cancer develop?
Cervical cancer is mainly caused by human papillomavirus (HPV), of which HPV types 16 and 18 cause about 70% of cervical and precancerous lesions.
What is human papillomavirus (HPV)?
Human papillomavirus (HPV) is A genus of papillomavirus A belonging to the family lactovacuole virus, which is A spherical DNA virus, and can cause the proliferation of human skin mucosa squamous epithelium. So far, more than 130 species have been isolated, and different types cause different clinical manifestations, which can be divided into:
(1) low-risk skin type: including HPV1, 2, 3, 4, 7, 10, 12, 15 and other related to common wart, flat wart, and plantar wart;
(2) skin high-risk types: including HPV5, 8,14,17,20,36,38 and associated with verrucous epidermal dysplasia, other malignancies also associated with possible HPV infection include: vulva cancer, penile cancer, anal cancer, prostate cancer, bladder cancer;
(3) low-risk type of mucosa, such as hpv-6, 11, 13, 32, 34, 40, 42, 43, 44, 53, 54, and infected with genital, anal, oropharyngeal, and esophageal mucosa;
(4) mucosal high-risk hpv-16, 18, 30, 31, 33, 35, 39 and cervical cancer, rectal cancer, oral cancer, tonsil cancer, etc.
Biological activity: HPV resistance is strong, can withstand drying and long-term preservation, heating or formalin treatment can be inactivated, so high temperature disinfection and 2% glutaraldehyde disinfection can be inactivated.
What are the symptoms of cervical cancer to watch for
Women have "bleeding" outside their periods
If a woman is found to have "bleeding" without reason when not menarche, or bleeding in the same room, these conditions may be related to cervical lesions, lesions invading blood vessels will cause irregular bleeding, the more severe the lesion, the more frequent and severe the bleeding.
When this "signal" occurs, it is recommended to go directly to the hospital for cervical screening to confirm the condition of the lesion, and if necessary to do a biopsy, which is to take a small amount of cervical tissue at the suspected lesion site of the cervical for detection.
At this stage of the disease, if the infection continues, it will develop into cervical cancer. At this time, it is necessary to cooperate with the combined treatment of surgery and drugs. After the operation, it is necessary to properly regulate the immune system and suppress the retention and infection of the virus.
To find this signal, the main thing is to see if you have HPV.
During a simple HPV infection is the best time to turn to the negative, because HPV can be directly eliminated by human immunity, most women with good enough immunity can turn to the negative within 1 to 2 years, appropriately improve the immune system and in 3 to 6 months to clear.
For most women with low immunity, the immune system can be directly regulated by nutrition intake. Nutrients such as selenium, cordyceps militariae and sea cucumber peptide can protect immune cells and thus improve immune function.
How to prevent cervical cancer
1. Health issues
For women, keep regular, healthy sex in your life, not too early. For some adult women, it is important not to have too many sexual partners and to pay attention to sexual hygiene.

Women who do not want to have children should take good contraceptive measures, which can effectively reduce the risk of cervical cancer.
3. Keep good habits
If women want to prevent cervical cancer, they should give up smoking and drinking, pay attention to the nutrition and health of the diet, and ensure that the body can absorb enough nutrients. Having good living habits can effectively alleviate some of the adverse effects of pelvic congestion on cervical blood circulation. And in life to maintain enough exercise, exercise can make the body's immunity effectively better, to prevent the occurrence of disease is very beneficial.
4. Get the HPV vaccine
At present the most effective way to prevent cervical cancer is to vaccinate HPV vaccine, now there are two valence, four valence, nine valence HPV vaccine in China, women friends can according to their age and physical condition, choose to inject. At present, the price of bivalent vaccine is 608 yuan per injection, and the cost of three injections is the same, belonging to three doses of vaccination. Four valent one is 826 and one dose is also three doses. The price is 1326 yuan per injection and also three doses. The HPV vaccine is expensive for most people.
