Ask Your Partner to Quit Smoking as it Increases Lung Cancer Risk by Over 20%

“Husbands who smoke a lot increase their spouse’s risk of lung cancer by more than 20%”, says a new report published in the International Journal of Cancer.

It’s not just the smoke from your husband occupational exposure to secondary smoke also increases the likelihood of developing the lung cancer by a similar amount.

“This pooled analysis of two large studies of second-hand smoke and lung cancer provides firm evidence for a dose-response relationship between lung cancer risk and duration of exposure to second-hand smoke for the three main sources of exposure spousal, workplace and social,” wrote the authors of the international study.

“It provides more precise estimates of the effect of second-hand smoke on lung cancer risk in non-smokers from all sources than those previously obtained in individual studies and emphasizes the importance of protecting non-smokers from second-hand smoke”, added the authors.

The research study also claims that secondhand smoke increases the risk of both adenocarcinoma, and squamous and small cell carcinomas.

“The implications of reducing exposure to second-hand smoke go beyond the prevention of lung cancer in non-smokers, since such measures to reduce exposure to second-hand smoke also result in a decreased opportunity for smoking among active smokers and a subsequent reduction in active smoking levels,” say the authors.
