The development of cervical cancer in a year and a half depends on the local condition of the cervix. If there is a high-grade cervical precancerous lesion, it may develop into cervical cancer in a year and a half. If the original high-risk HPV infection does not occur, most of them will not develop into cervical cancer after one and a half years. It is very important for women to have regular cervical cancer screening to know whether there are cervical epithelial lesions through cervical cancer screening, so that once the lesions occur, they can be treated in time to reduce the incidence of cervical cancer, so screening is very important for women. It takes about eight years from the time of cervical high-risk HPV infection to the development of cervical cancer. If abnormalities are detected and treated in time during the eight years or so, basically cervical cancer will not develop.
