Myths about HPV
- Genital warts mean you get cancer – No. Warts are caused by a different type of HPV
- I did not have much sex so I probably will not have it – Wrong. The presence of HPV is not a sign that someone has slept with many people or cheated on a partner. You can get it during your first sexual intercourse – whether it's touching, penetrating sex, oral sex or sharing sex toys
- We use condoms so I'm totally protected – Wrong. Using condoms reduces the risk, but not entirely
- My current partner must give it to me – It is not mandatory. HPV may remain unnoticed in the body for years. This is a very common phenomenon and for most people it will never cause a problem
- Although the HPV vaccine protects against seven out of ten cases of cervical cancer, it does not offer complete protection. So, even if you had an HPV vaccine, it is very important to attend cervical screening
