Final answer:
Human Papillomavirus (HPV) is the virus associated with cervical cancer, and it is responsible for more than 90 percent of cervical cancer cases due to its ability to interfere with normal cell division and cause persistent infections that can lead to cancer.
Step-by-step explanation:
The virus associated with cervical cancer is the Human Papillomavirus (HPV). There are many oncogenic viruses linked to cancer, and HPV is one of the most notable as it can lead to cancer of the reproductive system in females. Oncogenic viruses like HPV are often spread through sexual contact and can cause persistent infections that may lead to cellular mutations and uncontrolled cell division. More than 90 percent of cervical cancer cases are caused by an infection with HPV, which interferes with normal cell division processes.
HPV infections can vary, as the HPV family includes over 100 related viruses. The specific characteristics of each strain influence the infection's outcome. When the HPV strain is oncogenic, it can hijack the host cell's machinery to produce more virus particles, sometimes leading to mutations that cause cancer.
