One or more high-risk types of Human papillomavirus are present in over 99.8% of cervical cancers.
Testing everyone who attends for cervical screening using a test for high risk HPV will pick up more cell changes and prevent more cancers than just examining the cells.
HPV stands for Human papillomavirus. This is a very common virus that most people will come into contact with at some time during their lives.
There are lots of different types of the virus most of which do not cause any problems. The different types are known by a number, for example HPV type 18.
In most people, HPV does not cause any problems, as the body will get rid of the virus on its own.
Some types of HPV can cause cell changes on the skin. These are called either high risk or low risk types depending on what changes they can cause.
High-risk types of HPV can cause changes in the cells of the skin covering the neck of the womb (cervix). These cell changes are called cervical intraepithelial neoplasia (CIN). Most CIN will go away on its own, but sometimes it can get worse and become cervical cancer.
High-risk types of HPV can also cause changes in the skin cells in other parts of the body.
Types 16 and 18 are the most common high-risk types, but there are 14 high-risk types that are tested for in cervical screening.
Low risk types of HPV can cause warts. Cervical screening does not test for low risk types as they will not cause cervical cancer.
HPV is spread by skin to skin contact. For HPV in the cervix, this is through sexual contact. This can be by having full sex, oral sex, genital touching or sharing sex toys.
Yes. Most people are probably infected at some stage in their lives but never know. In most cases, the body’s own defences (immune system) get rid of the virus.
The virus does not cause any symptoms even if there are cell changes on the cervix. This is why cervical screening is important.
The HPV virus can lie dormant (sleeping) for many years and may never cause any cell changes. If it is found on a screening test, we cannot say how long it has been there. The virus might cause cell changes many years later. This is why it is important to keep going for screening when you are invited, even if your tests have always been normal.
HPV is a virus, which means that it cannot be treated with antibiotics. In most people, the body will get rid of the HPV on its own. If you have cell changes caused by the virus, these may need to be treated in a colposcopy clinic. Most minor cell changes will go on their own without treatment.
Anyone can get HPV and can pass it on to partners. High risk HPV is also linked to other cancers including head, neck, genital and anal cancers.
Using condoms can reduce your risk, but does not give you complete protection, although condoms do protect against other infections. Going for cervical screening will tell you whether you have the virus in your cervix and whether it is causing any cell changes.
No, there is not any evidence that having HPV has any effect on future fertility.
No. AIDS (Acquired Immune Deficiency Syndrome) is caused by a different virus called HIV (Human Immunodeficiency Virus). People with HIV may find it harder to get rid of HPV and will need screening more often.
Smoking makes your body’s immune system weaker. This makes it much more difficult for your body to get rid of the virus.
From September 2019 everyone aged 12-13 is offered the vaccination. However, it is possible to develop cell changes despite having had the vaccine. People who have been vaccinated should still have their cervical screening tests when invited.
Some cervical cancers are caused by different HPV types than the vaccine covers. This means that the vaccine cannot prevent every case. This is the reason we still advise you to have cervical screening, even if you have been vaccinated.
Yes – the vaccine covers the most common (high-risk) types of the virus, which cause around 70% of cervical cancers. The vaccine is given to girls and boys aged 12-13 because it should be given before they might come into contact with HPV.
