In addition the following 6 types of human population is easy to suffer from cervical cancer,
1, Human papillomavirus (HPV) infection, 96.7% cervical cancer patients had HPV infection;
2, genital herpes virus infection; multiple sexual partners: a study in the United States showed that: sexual partner number greater than or equal to 10 persons, in cervical cancer new cases accounted for 36%, indicating that multiple sexual partners and in situ cervical cancer and cervical cancer were significantly correlation;
3, 18 years old the prevalence of sexual life is 3 times higher than 21-25 years old, 7 times higher than the above 26 years old. Because the reproductive tract development is not yet mature, the stimulation of carcinogenic factors is more sensitive, once infected with certain bacteria or viruses, and easily lead to cervical cancer.
4, in particular, moderate and severe atypical hyperplasia, cervical erosion who, if not active treatment may also translate into cervical cancer;
5, smoking and low income population is the high incidence of cervical cancer.
Recommended that women do a check every year
For cervical cancer prevention, early detection, early treatment is the key. According to reports, at present international accreditation scheme for "cervical cancer three-step screening programme", the first step for cervical cytology, the second step as the human papilloma virus checking (i.e. HPV test). The third part for colposcopy.
"We recommend that women per year to do a, according to economic conditions to select screening programs, at least to do the first step, of course, the first step and the second step combine to do better, screening rate reached more than 95%." Doctors said that 3 consecutive years of examination and normal persons can be screened for 3 years.
And the about cervical cancer screening technology, the medical profession is also presented a new theory, three ladder traditional cervical cancer screening program was the second step and first step reversed, the first HPV screening and detection of HPV for patients with positive screening, in order to improve the rate of missed diagnosis. "There is a relatively large percentage of missed diagnosis, the missed diagnosis rate of 20% - 30%." Guan Songqing said, HPV screening of human interference factors are relatively small, the possibility of missed diagnosis is relatively small, but the HPV test for patients with a small number of patients with cervical cancer.
What is worth mentioning is that after the age of 30 women in cervical cancer high risk period. The doctor advised, the women of this age should strengthen the inspection frequency. After the age of 60 to check the time interval can be moderately elongated.
Vaccine and can not be 100% prevention
There is also a way to effectively prevent cervical cancer - vaccination of cervical cancer (that is, HPV vaccine). But how effective?
Experts said that at present, cervical cancer vaccine and can not intercept all HPV type of virus, can reduce the risk of cervical cancer, but can not prevent cervical cancer 100%. "And the vaccine is only for people who have no sexual life."
"HPV vaccine from 2006 listing, to now less than 10 years, its long-term preventive effect is not yet known." Experts said the United States, the United States and Europe, a number of large-scale investigation is still ongoing, the genetic recombinant vaccine whether the human body has not yet been tested.
