In case of cervical cancer in situ, it can be clinically cured by timely removal of the uterus and surgical treatment. Since there are many patients with in situ cancer surviving for 30 or 40 years, it is especially important for women to be screened for cervical cancer. It is recommended to have cervical cancer screening once a year, and if abnormalities are found, timely treatment can be given to prevent the occurrence of cervical cancer. At present, only cervical cancer has been identified as the cause of cancer worldwide, and it is caused by high-risk HPV infection. This is why it is particularly important for cervical screening, clinically speaking. Even in the absence of discomfort, it is very beneficial to women’s health to have an annual checkup to detect abnormal problems and then deal with them in a timely manner.
