[The role of viruses in the etiology of bladder cancer].

Currently, debate continues about the etiological role of pathogens, in particular viruses, in the development of bladder tumors, their impact on the rate of recurrence and invasive and metastatic forms. The etiological role of high-risk human papillomavirus (HPV) in squamous carcinoma of the cervix and upper respiratory tract is considered proven. However, some published studies show the role of oncogenic HPV in causing bladder cancer, its invasiveness and metastasizing. The review is dedicated to examining the role of HPV in the carcinogenesis of bladder cancer.
