Smoking and human papillomavirus

Teaching Brief® - MedPage Today: "Review
STOCKHOLM, Nov. 17 -- Smoking and human papillomavirus (HPV) may work together to increase the risk of cervical cancer in situ, according to researchers here.
In a case-control study, smokers infected with HPV-16, the most prevalent of the oncogenic types, had 14 times the risk of progressing to cancer than did smokers who weren't carrying the virus, found Anthony Gunnell, a doctoral candidate at the Karolinska Institute here.
These HPV-16-positive smokers also had more than double the risk of non-smokers with an HPV-16 infection, Gunning and colleagues reported in the November issue of Cancer Epidemiology, Biomarkers & Prevention. "
