True healingme4me, but over 90% (I forget the actual figure) of cervical cancer is caused by an STD that has no other symptoms for most people. For that reason if you have been with a single (or less) sexual partner for more than a set amount of years, your cervical cancer screening recommendation drops to every three years. That's why there's a cervical cancer vaccine- it protects you from HPV, the virus that can cause cervical cancer to form. It you've had the same (or none) partner over a long period of time and have not developed cervical cancer, you are at very low risk.
