How long does it take for precancerous lesions to develop into cervical cancer?

Cervical precancerous lesions can be divided into mild precancerous lesions and severe precancerous lesions. If mild precancerous lesions are not treated in time, it takes 3 to 5 years for severe precancerous lesions to develop. At this time, if aggressive treatment can prevent the development of cervical cancer. If severe precancerous lesions are not treated in time, it usually takes 5 years for cervical cancer to develop. Therefore, it takes about ten years from mild cervical cancer to cervical cancer. This time is relatively long. As long as it is detected early and treated early, it can be cured completely.
