                  Reasons why women need regular screening for cervical cancer

                  • 1. Cervical precancerous lesions and early cancers are mostly asymptomatic, and gynecological examinations are difficult to detect.
                  • 2. When symptoms occur, more than 80% of them are invasive cancers, which are difficult to cure.
                  • 3. From HPV infection to cervical precancerous lesions can be as long as 5-13 years, at this stage, lesions can be found to be cured

                   

                  Reasons why women need regular screening for cervical cancer

                  • 1. Women who have sex for more than three years or over 21 years of age.
                  • 2. Cervical scraping found suspected cells and pathological examination found atypical cell proliferation.
                  • 3. Women who have sex too early (referring to those who have sex before the age of 18) are early married and early childbearing. The incidence of cervical cancer in women with sexually transmitted diseases such as syphilis and gonorrhea is six times higher than that in normal women.
                  • 4. Multiple sexual partners, a US study shows that multiple sexual partners are significantly associated with cervical cancer in situ and cervical cancer. I or my husband has sexual disorder, the husband has a long foreskin or phimosis.
                  • 5. Patients with chronic cervical diseases, such as cervicitis, cervical erosion, leukoplakia, cervical laceration, etc.
                  • 6. Age factors, women over 30 years old with high-risk HPV are 116 times more likely to develop severe precancerous transformation than non-infected women. Women over 40-50 years old are at increased risk of cervical cancer.
                  • 7. People with low immunity, such as those infected with HIV, those with poor nutritional immunity, pregnant women or those receiving chemotherapy, may be more likely to develop higher infections.

                   

                  Precautions before inspection

                  • 1. Do not wash the vagina within 48 hours before the examination, and do not use intravaginal drugs such as contraceptive ointment.
                  • 2. It's better not to have sex within 48 hours before the check-up.
                  • 3. Do not apply acetic acid or iodine solution before examination
                  • 4. It's inappropriate to check during menstruation

                   

                  How to detect HPV infection?

                  At present, advanced molecular biological detection technology: HPV genotyping kit can simultaneously accurately and rapidly detect the most common 19 high-risk HPV viruses and 7 low-risk HPV viruses, and determine the degree of infection, the detection rate of cervical precancerous lesions was over 92%, and the negative predictive value was as high as 99.6%. Through this test, the examinee can know whether he belongs to the high-risk group. At the same time, it can help doctors to formulate correct and effective follow-up and treatment programs.

                   

                  Significance of HPV Gene Detection

                  • 1. The risk of persistent HPV infection in the same high-risk type is higher. It is now clear that persistent HPV infection in the same high-risk type has a higher risk of high cervical lesions. Detection of HPV genotyping is helpful to determine whether a patient is persistently infected with the same genotype or repeatedly infected with different genotypes.
                  • 2. Different high-risk types of HPV infection have different clinical treatment schemes: different high-risk types of HPV have different carcinogenic risks, and different high-risk types of HPV infection have different clinical treatment schemes.
                  • 3. For Atypical Squamous Cells of Undetermined Signification(ASCUS), HPV detection is the preferred method of shunting. Separate potential cases of cervical cancer risk, guide the rational use of colposcopy, improve the diagnostic rate and reduce the rate of missed diagnosis.
                  • A large number of studies have shown that HPV detection is superior to cytological examination in the follow-up of cervical lesions after treatment. During the follow-up of patients with early cervical lesions after treatment, HPV genotyping is helpful to determine whether the patients are persistent infection of the same genotype or repeated infection of different genotypes.
                  • HPV genotypes and infection rates of cervical lesions in different countries and populations are different, which can guide the development and operation of HPV vaccine.

                   

                  How to analyze HPV test results

                  If the HPV DNA test results are negative, that is, no HPV virus infection, and the cytological test results are negative, then there is no risk of cervical cancer in 3-5 years.

                  Positive HPV DNA test results, that is, a significant increase in the risk of cervical cancer. But we need to understand that not all women infected with HPV virus will develop cervical cancer, so we need to further check whether cervical cells have precancerous lesions. If cytological abnormalities have occurred, they should be treated immediately; if no lesions have occurred, they should also be followed up regularly (6-12 months) to track the status of virus infection, which can not be ignored.
