Smoking Associated With
Increased Risk Of Cervical Cancer Among Human Papillomavirus-Infected Women September 18, 2002 (Journal of the National Cancer Institute) -- Current and past smoking may
increase the risk of cervical cancer among women who have been infected with the human
papillomavirus (HPV), according to a study in the September 18 issue of the Journal
of the National Cancer Institute. Philip E. Castle, Ph.D., of the National Cancer Institute, and his
colleagues looked at the association between various risk factors and cervical cancer
among 1,812 women who had tested positive for oncogenic HPV DNA. Oral contraceptive use
and history of live births were not associated with the risk of cervical cancer or its
precursor, cervical intraepithelial neoplasia grade 3 (CIN3). However, former and current
smokers appeared to have an increased risk of cervical cancer and CIN3 compared with women
who never smoked.
