Smoking Behaviors in Survivors of Smoking-Related and Non–Smoking-Related Cancers

Key Points Question Among adult cancer survivors, do cigarette smoking behaviors vary according to whether the cancer was smoking related or not smoking related? Findings This cross-sectional study found that, in the 2017 US National Health Interview Survey, which included 26 742 respondents aged 18 years or older, current smoking prevalence was higher among smoking-related cancer survivors compared with non–smoking-related cancer survivors (19.78% vs 10.63%). After cancer diagnosis, the odds of continued cigarette smoking were twice as high among those with smoking-related cancers compared with those with non–smoking-related cancers. Meaning Compared with non–smoking-related cancer survivors, smoking-related cancer survivors have a higher risk of being cigarette smokers and of continuing smoking.
