Which virus is most commonly linked to cervical cancer due to chronic infection?

• A. Hepatitis C virus
• B. Human immunodeficiency virus (HIV)
• C. Human papillomavirus (HPV)
• D. Herpes simplex virus

Answer: (C)

Human papillomavirus (HPV) is the virus most commonly linked to cervical cancer due to chronic infection. HPV is a group of more than 150 related viruses, of which at least 14 types are known to cause cancer. Particularly, high-risk types like HPV 16 and HPV 18 are responsible for the majority of cervical cancer cases. Infection with these high-risk strains can lead to the development of precancerous lesions in the cervix and, ultimately, cervical cancer if not detected and managed appropriately.

The association between HPV and cervical cancer is well-established, making vaccination against HPV a critical public health initiative to reduce the incidence of this type of cancer. In contrast, the other viruses listed are not primarily associated with cervical cancer. For instance, hepatitis C virus is primarily linked to liver cancer, while HIV increases the risk of various cancers due to its immunosuppressive effects but is not directly linked to cervical cancer like HPV. Similarly, herpes simplex virus is more associated with genital herpes and other complications but does not play a significant role in cervical carcinogenesis.
