Carcinogenesis and epidemiology of cervical cancer: The hallmark of human papillomavirus‐associated cancer

Abstract

AbstractCervical cancer affects women worldwide and is the most common human papillomavirus (HPV)‐associated cancer. Carcinogenesis caused by HPV results in specific cancer behavior because of the underlying viral infection. The mechanism and timing of the transformation from viral infection to cancer cells have been elucidated in detail. Treatments for this cancer are based on its characteristics and are being implemented. Moreover, HPV infection is widespread worldwide and is transmitted through sexual activity. Although the HPV vaccination is the most effective strategy of preventing cervical cancer, it is not feasible to vaccinate the entire human population especially in low‐ and middle‐income countries. In order to consider the next step for HPV vaccination, we need to understand the characteristics of HPV carcinogenesis and cervical cancer. Additionally, treatment aimed at preservation of reproductive function in patients with cervical cancer is often required, as the cervix is a reproductive organ and because the disease is more prevalent in the adolescent and young adult generation. Thus, there are still many challenges in the diagnosis, treatment, and prevention of cervical cancer.
