Final answer:
HPV types 16 and 18 are most often associated with cervical cancer, accounting for over 70% of diagnoses.
Step-by-step explanation:
The human papillomavirus (HPV) types most often associated with cervical cancer are HPV 16 and HPV 18. These two strains are classified as high-risk HPV types due to their potential to cause cancer, and they have been linked to more than 70% of cervical cancer diagnoses. While high-risk HPV types can potentially be cleared by the immune system over time, persistent infections with HPV 16 or HPV 18 can lead to the development of precancerous changes in the cells of the cervix, increasing the risk of cervical cancer.
