Cervical cancer is the third most common cancer in women in the world, the disease in Asia, up to 50% mortality rate. 99% of cervical cancer are the human papilloma virus ( HPV ) caused. By HPV testing, cervical cancer can be avoided.
Infected with high-risk HPV virus
High likelihood of cervical lesions
Worldwide each year nearly 50 million women are diagnosed with cervical cancer, cervical cancer is almost all the human papilloma virus (HPV) caused. HPV infection is a specialized human epidermal and mucosal squamous epithelium of the virus, the main route of transmission to sexual activity. HPV infection is more common in women, the data show that in a certain stage of life, every five women will be infected have four HPV. Now known to have more than 100 different types of HPV, most of which HPV types are considered "low risk", not associated with cervical cancer. But there are 14 types of HPV are classified as "high risk" in which the two highest risk strains of the virus - HPV 16 and HPV 18 can result in about 70% of cervical cancer cases. Compared to women not infected with HPV, the virus strains carrying these two women even normal cytology results, the possibility of developing cervical lesions also 35 times higher.
Body asymptomatic latent decade
Routine screening is important
At the recent Asia - Oceania genital infections and cancer research organizations annual meeting, Professor Emeritus of Pathology and Cell Biology, Medicine, Columbia University, New York Thomas Wright said that, generally speaking, because they can not see the symptoms of cervical precancerous lesions, most women do not know they are sick. "Our study found that even normal cytology results, if positive HPV16/18 every 10 women there who still have a cervical precancerous lesions." Professor Wright believes that through early detection of cervical cancer can be prevented , there is sufficient evidence to prove this. HPV can lurk in the body in view of a decade or even longer, and do not have any symptoms of HPV testing as part of the routine screening is important, this can increase the rate of early detection and ultimately the prevention of cervical cancer.
Chinese Academy of Engineering, Union Hospital, director of the King and Professor Lang also said that the cure rate of cervical precancerous lesions up to 98%, but once the development and spread of cancer to other organs, only 20% of women survive more than five years of energy. He appealed to enhance the use of HPV screening tests, and encourage women to undergo regular high-risk HPV testing, especially HPV 16 and 18 detection, early detection of risk to help, but also an effective way to Asian women cervical cancer incidence and mortality reduction .
HPV DNA testing is more accurate
According to experts, the existing cervical cytology screening method is mainly through test results affected by many subjective factors, studies have shown that a single cytology is not enough to evaluate the risk of women suffering from cervical cancer. High-risk HPV DNA testing is molecular etiology-based detection methods, can be more objectively assess whether subjects women have cervical cancer or precancerous lesions of the presence of a high risk of progression to precancerous lesions, "high-risk HPV DNA testing allows Doctors can confidently judge. negative results on behalf of women have a lower risk of cervical cancer, which extend security screening interval. women can on the basis of conventional cytology screening, requested a doctor be high-risk HPV testing.
