Smoking increases rectal cancer risk to the same extent in women as in men: results from a Norwegian cohort study.

Smoking is associated with increased predisposition to rectal cancer in both men and women.

This study examined whether smoking affects rectal cancer development risk in both men and women. Researchers tracked the smoking habits of 602,242 men and women recruited from 4 Norwegian Health Survey cohorts. The rectal cancer hazard ratio of each participant in this study was also assessed.

Researchers discovered that the chances of developing rectal cancer was higher in smokers than in non-smokers. According to this study, a 25% increase in the risk of rectal cancer was found to be associated with men and women who were smokers. The authors of this study concluded smoking may contribute positively to the development of rectal cancer in both men and women.
