The time of atypical squamous cell carcinoma is mainly related to the cause of the disease and the patient’s physical condition, which should be analyzed on a case-by-case basis and should not be generalized. Atypical squamous cells are cervical cells with a small amount of cell morphology changes, which are not typical squamous cells. If it is a small amount of atypical squamous cells caused by chronic cervical inflammation, it is usually not carcinogenic. However, if it is atypical squamous cells caused by cervical intraepithelial neoplasia, the time of carcinogenesis is usually about 5-10 years or even longer, but the exact time needs to vary from person to person. However, if the patient blocks HPV infection in time, it is possible that it will not become cancerous. Therefore, patients with atypical squamous cells should go to the medical oncology department of a regular hospital in time for examination by a professional doctor to clarify the cause and then treat the disease.
