Some HPV (human papillomavirus) infections can go away on their own. In most people, the body’s immune system fights HPV infections and clears them from the body. 

Sometimes HPV infections can last longer. A longer infection with a “high-risk” HPV type can turn into cancer. 

It can take 3 to 7 years for abnormal changes in the cells on the cervix to become cancer. The purpose of cervical cancer screening is to find these changes while they are still easily treated. Women with “low-grade” changes can be tested over time to see if the cells go back to normal. Women with “high-grade” changes can get treatment to have the cells removed from the cervix.
