In addition to laryngeal cancer and malignant tumors such as cervical cancer and oral cancer, HPV can also cause a number of other benign lesions (note that benign lesions are for malignant tumors, not that benign lesions are not serious). A growing number of studies have shown that among HPV-associated diseases, different diseases can be caused by one type of HPV or multiple types of HPV, and conversely, the same type of HPV can cause different diseases. The most common benign lesions caused by HPV are in the skin and anogenital area, and most are caused by low-risk HPV viruses. 1, condyloma acuminata In all HPV types, there are more than 40 kinds of can infect the human anogenital mucosa, often cause condyloma acuminata and other genitourinary tract diseases, the most common type is HPV6, 11, 40, 42, 43, 44 type. The most common types are HPV6, 11, 40, 42, 43 and 44. HPV6 and 11 are the most dominant HPV types and are absolutely dominant in countries around the world. 2, recurrent respiratory papillomatosis Recurrent respiratory papillomatosis is a viral disease, usually caused by HPV6 and 11, often accompanied by exophytic airway damage, although morphologically a benign disease, but there are potentially malignant consequences because of the involvement of the airway and the risk of malignant transformation. 3, common warts, flat warts, filiform warts, perineural warts, plantar warts, etc. The common benign skin proliferative diseases mentioned above are also associated with some HPV subtypes.
