Cervical cancer begins with unusual changes in your tissue. Most cases are linked to infection with human papillomavirus (HPV). Other factors that may cause the DNA mutation of normal cervical cancer can also lead to risk of cervical cancer.
You might be at higher risk of cervical cancer if you:
Started having sex before age 16 or within a year of starting your period
Have multiple sexual partners
Take birth control pills, especially for longer than 5 years
Have a weakened immune system
Have a sexually transmitted disease (STD)
