It is difficult to know whether there has been human papillomavirus infection through self-examination. If it is a low-risk HPV type 6 or HPV type 11 infection, when grayish-white cauliflower-like redundant organisms appear on the vulva, finding this condition by oneself may be caused by low-risk HPV infection. However, high-risk HPV infection often does not have any clinical symptoms, so it is difficult to know whether there is such HPV infection through self-examination. It is recommended that women should have cervical cancer screening once a year to know whether they have HPV infection and whether they have cervical epithelial lesions, which should be given timely treatment.
