In the meantime, I am fascinated with this article from the American Journal of Epidemiology, about a potential correlation between smoking and HPV:
Is Smoking an Independent Risk Factor for Invasive Cervical Cancer?
The strong correlation between smoking and exposure to oncogenic human papillomaviruses (HPVs) has made it difficult to verify the independent role of smoking in cervical carcinogenesis. .... The point estimates increased with increasing age at diagnosis and increasing cotinine level. This study confirms that smoking is an independent risk factor for cervical cancer/SCC in women infected with oncogenic HPVs. These findings emphasize the importance of cervical cancer prevention among women exposed to tobacco smoke.
Evidence that demonstrates the negative consequences of smoking just keep piling up. And when I see how tobacco uniquely effects women, I get more anxious for my friends who smoke. And angry at the tobacco companies ... but I won't go down that route just now.
