HUMAN PAPILLOMAVIRUS INFECTION AND CERVICAL CANCER (OWERWIEW)

Аннотация

Viral infections are responsible for 15–20% of all human cancers. Infection with oncogenic viruses can contribute to various stages of carcinogenesis. Despite effective screening methods, cervical cancer continues to be a major public health problem. There are large differences in morbidity and mortality from cervical cancer by geographic region. The age-specific prevalence of HPV varies widely in different populations and has shown two peaks of HPV positiveness in young and older women. Around the world, there have been many studies on the epidemiology of HPV infection and oncogenic properties due to different HPV genotypes. However, there are still many countries where population prevalence has not yet been determined. Moreover, screening strategies for cervical cancer differ from country to country. Organized cervical screening programs are potentially more effective than opportunistic screening programs.
