HPV infection is clinically divided into low-risk HPV infection and high-risk HPV infection. Low-risk HPV infection often results in the growth of redundant organisms on the skin, which can be treated with laser therapy, cryotherapy or surgery, and the excised redundant organisms must be sent for pathological examination. High-risk HPV infection has no good treatment so far. High-risk HPV infection in the cervix, if it is persistent, may lead to cervical epithelial lesions and even develop into cervical cancer. It is very important for women to have regular cervical cancer screening so that once cervical lesions are detected, they can be treated in time to reduce the chance of cervical cancer.
