Cervical cancer is caused by persistent high-risk HPV (human papillomavirus) infection. “Cervical cancer is caused by persistent high-risk HPV (papillomavirus) infection. “Cervical erosion” is “ectropion or displacement of the columnar epithelium of the cervix”, which is a physiological change in the overlying epithelium of the cervix in women. Different degrees of “celiac disease” (mild, moderate or severe) are not associated with the development of cervical cancer. At present, TCT examination does not indicate precancerous lesions, and bleeding after coitus is considered to be cervical inflammation, which can be observed with medication for a short period of time, and HPV test can also be done. If the result is negative, there is no need to worry about cervical cancer for the time being, and regular checkups can be done.
