Which women are at increased risk for having an abnormal Pap smear?
A number of risk factors have been identified for the development of cervical cancer and precancerous changes in the cervix. • HPV: The principal risk factor is infection with the genital wart virus, also called the human papillomavirus (HPV), although most women with HPV infection do not get cervical cancer. (See below for details). About 95%-100% of cervical cancers are related to HPV infection. Some women are more likely to have abnormal Pap smears than other women. • Smoking: One common risk factor for premalignant and malignant changes in the cervix is smoking. Although smoking is associated with many different cancers, many women do not realize that smoking is strongly linked to cervical cancer. Smoking increased the risk of cervical cancer about two to four fold. • Weakened immune system: Women whose immune systems are weakened or have become weakened by medications (for example, those taken after an organ transplant) also have a higher risk of precancerous changes in the cervix
