Some patients with atypical squamous cells may experience symptoms of inflammation such as increased vaginal discharge that turns yellow and becomes pus and snot-like. Atypical squamous cells are a condition reported during cervical cancer screening and generally refer to abnormal squamous epithelial cells. Atypical squamous cells may be caused by inflammation of the cervix, precancerous lesions of the cervix, and other causes. Patients may present with signs of inflammation such as increased vaginal discharge that turns yellow and becomes pus and snot-like. Some patients may not have any symptoms. Atypical squamous cells refer to abnormalities in the squamous epithelium of the cervix. Although this abnormality is only an abnormality in cell morphology and does not reach the level of diagnosis of cancer cells, it is still necessary to undergo a test for human papillomavirus (HPV) infection so as to determine the presence or absence of HPV infection and other conditions. If atypical squamous cells are found in the clinic, one should go to the hospital in time. Doctors will clarify the cause of the disease and the severity of the disease through relevant examinations, and carry out targeted treatment according to the specific situation.
