Researchers identify new genetic risk factors for persistent HPV infections
Human papillomavirus (HPV) is the second most common cancer-causing virus, accounting for 690,000 cervical and other cancers each year worldwide. While the immune system usually clears HPV infections, those that persist can lead to cancer, and a new finding suggests that certain women may have a genetic susceptibility for persistent or frequent HPV infections. These genetic variants could raise a woman's risk of getting cervical cancer from a high-risk HPV infection.
