HPV and cervical cancer

What is HPV?

HPV is a common virus. It is spread by skin-to-skin contact. There are more than 200 types of HPV and about 8 in 10 people will get HPV during their lifetime.

Around 40 types of HPV affect the anus (back passage) and genitals. 14 of these are known as high-risk HPV. This is because they are linked to some cancers.

Nearly all cervical cancer (99.7%) is thought to be caused by high-risk HPV. Over 7 in 10 of these are caused by high-risk types 16 and 18.

Will everyone with high-risk HPV get cervical cancer?

No, having high-risk HPV does not mean you will get cervical cancer.

During our lives, 8 in 10 of us will get some type of HPV. It usually goes away without any problems. Most of us will never know we had it. Around 9 in 10 HPV infections clear within 2 years.

For a small number of women and people with a cervix, HPV will remain in their body. This is called a 'persistent HPV infection' and it can lead to cell changes in the cervix.

What happens if you get high-risk HPV?

 

 

 

You get high-risk HPV through skin-to-skin sexual contact,
or by sharing sex toys

 

 

 

 

High-risk HPV infects epithelial cells in your cervix.
These are the cells that are taken at cervical screening (previously called a ‘smear test’) and sent to a laboratory.

Epithelial cells are always making copies of themselves. High-risk HPV might cause epithelial cells to change (become abnormal), so they don't look like normal cells. When these changed cells copy themselves, the new cells won’t look normal either.

 

In the UK, your cervical epithelial cells that are taken at cervical screening are tested for high-risk HPV first. If high-risk HPV is found, your cells are then looked at under a microscope to see if they have changed.

What happens when HPV is cleared from your body? (9 in 10 people)

 

 

 

Your immune system fights the HPV infection.
It is usually gone within 2 years.

 

 

 

 

What happens when HPV is not cleared from your body? (1 in 10 people)

 

 

Your immune system cannot get rid of the HPV. This is called a persistent HPV infection. The HPV may then cause the epithelial cells to change. Changed cells can make copies of themselves and the new cells will also be different. They might turn into cervical cancer over time if they are not monitored or treated.

 

 

Going for cervical screening means HPV and cell changes can be found early, so most changed cells will not turn into cervical cancer. However, we understand that HPV and cell changes can be worrying.

Why can’t everyone get rid of HPV?

We don’t know exactly why. Scientists think it might be to do with the type of high-risk HPV that someone has. It might be affected by your immune system — some people’s bodies find it easier to fight HPV than others. They also think some lifestyle habits, like smoking, can make it hard for your body to clear HPV. It is important to remember that cervical screening can help find high-risk HPV and cell changes early.

How do I reduce the risk of high-risk HPV turning into cancer?

Going for cervical screening when invited is the best way to find cell changes early. They can then be monitored or treated.

Although cervical cancer is rare, it is important to be aware of the symptoms. These include:

• vaginal bleeding that is unusual for you — including after the menopause, after sex, or between regular periods
• changes to vaginal discharge — it may start to smell bad or have blood in it
• pain or discomfort during sex
• unexplained pain in your lower back or between your hip bones (pelvis).

These symptoms can be caused by a lot of things. They do not mean you have cervical cancer. But you know your body best — it is important to contact your GP if you have any of these symptoms or notice anything unusual for you.
