title: [Cancers from tobacco smoke].
abstract: The proximity of smokers exposes non-smokers to the inhalation of tobacco smoke. The existence of this absorption has been established by assays of blood nicotine concentrations or urinary thiocyanate concentrations, in volunteers: proximity with an individual who smokers approximately ten cigarettes is equivalent to smoking one cigarette. Consequences of this passive smoking are not negligible. Two studies, one Japanese and one Greek, have shown that the risk of lung cancer in wives of smokers is twice that in non-smoking women married to non-smokers, even though various American studies seem more reassuring. Another risk of cancer exists in the offspring of mothers who smoked during their pregnancy, with a rate of 14.9 x 10(5) if the mother smoked, versus 11. 4 x 10(5) if she didn't. Experimental rates of cancer in hamster fetuses confirm this risk.
