When you’re exposed to genital human papillomavirus (HPV), your immune system usually prevents the virus from doing serious harm. But sometimes, the virus survives for years. Eventually, the virus can lead to the conversion of normal cells on the surface of the cervix into cancerous cells.
HPV can cause cervical and other cancers including cancer of the vulva, vagina, penis, or anus. It can also cause cancer in the back of the throat, including the base of the tongue and tonsils (called oropharyngeal cancer). Cancer often takes years, even decades, to develop after a person gets HPV.
Which virus greatly increases the chances of developing cervical cancer?
HPV causes nearly all cervical cancers. About 70% of HPV-related cervical cancer is caused by HPV-16 or HPV-18. However, most genital HPV infections will not cause cancer. Smoking can also raise the risk of cervical cancer in women with HPV.
Which virus plays an important role in the development of cervical cancer?
Key facts. Human papillomavirus (HPV) is a group of viruses that are extremely common worldwide. There are more than 100 types of HPV, of which at least 14 are cancer-causing (also known as high risk type).
What happens to your body when you have cervical cancer?
What Is Cervical Cancer? Cervical cancer happens when cells change in women’s cervix, which connects thier uterus with vagina. This cancer can affect the deeper tissues of their cervix and may spread to other parts of their body (metastasize), often the lungs, liver, bladder, vagina, and rectum.
What kills HPV virus?
HPV can clear up naturally – as there is no cure for the underlying HPV infection, the only way to get rid of HPV is to wait for the immune system to clear the virus naturally.
What percentage of cervical cancer is caused by HPV?
In general, HPV is thought to be responsible for more than 90% of anal and cervical cancers, about 70% of vaginal and vulvar cancers, and more than 60% of penile cancers.
How does Oncovirus cause cancer?
Experts don’t fully understand how most known oncoviruses cause cancer. What is known is that viruses highjack cells and insert their own DNA or RNA into the host cell. This can cause the host cells to become cancerous.
Who is most at risk for HPV infection?
The risk is most likely affected by increasing the chances of exposure to HPV.
- Becoming sexually active at a young age (especially younger than 18 years old)
- Having many sexual partners.
- Having one partner who is considered high risk (someone with HPV infection or who has many sexual partners)
Who is at greatest risk for having HPV?
Numerous studies have demonstrated an increased risk of HPV infection at younger ages—the highest prevalence of HPV occurs among adolescents and young adults between the ages of 15 and 25,20,24–26 and it is believed that more than 75% of new HPV infections occur in individuals of this age range.
