Hi Maria, thses cell changes can occur naturally during adolescence which is why in England smears are not done before 25. They can go back to normal by themselves. In sexually active women they are mostly caused by one of the Human Papilloma Virus or HPV for short And can develop into cancer. There is a vaccination programme available now for teenage girlfoot protect against the highest risk strains of HPV.
