Bladder cancer is more likely to occur in current and former smokers than in never smokers.
This research work studied the relationship between tobacco smoking and the incidence of bladder cancer. A team of researchers at the National Cancer Institute assessed the smoking status of 467,528 men and women and estimated the bladder cancer odds ratio of each subject in the study population.
The research team found out that former and current smokers had higher chances of developing bladder cancer than never smokers. The results of this study further strengthen the evidence that tobacco smoking may be a contributing factor to the development of bladder cancer.
