What can a woman do to decrease her risk of getting cervical cancer?

One sexual partner. While the chances of dysplasia/cancer are low when you have only have a single sexual partner, your partner may not have only have a single partner, and therefore could infect you with hpv, the most common cause of cervical cancer. Do a pap smear and you will know if you are at risk. Using condoms or other barrier methods during sex will decrease your risk.
Pap smears. It is vital that women get regular pelvic examinations and pap smears to help find cervical cancer early. The cervical cancer vaccine is an option now as well.
