Final answer:
HPV high-risk strains, especially types 16 and 18, can cause precancerous changes in cervical cells, potentially leading to cervical cancer. Early detection through Pap tests and preventive vaccines like GARDASIL are crucial in managing the risk.
Step-by-step explanation:
Human papillomavirus (HPV) strains are categorized into high or low risk with regard to their cancer-causing potential. The high-risk strains of HPV, particularly types 16 and 18, are responsible for the majority of cervical cancer cases. If a persistent infection by these high-risk HPV types occurs, it can lead to the development of precancerous changes in the cells of the cervix. These changes can eventually progress to invasive cancer if not detected and treated early through screening methods like a Pap test. Vaccines, such as GARDASIL, are available to prevent HPV infection and significantly reduce the risk of developing cervical cancer.
