Risk of bladder cancer in smokers of e-cigarette smokers as well as traditional cigarettes
Data from a study looking at the link between how much a person smokes and whether they survive bladder cancer have also shown a link between the use of e-cigarettes and the risk of getting bladder cancer. The data were presented at the 112th Annual Scientific Meeting of the American Urological Association (AUA) on 12-16 May 2017.
Cigarette smoking is a well-known cause of bladder cancer, and the study found that the more cigarettes a person with bladder cancer smoked the lower their chances of survival were, and that even a small reduction in the amount of cigarettes smoked made a positive difference.
The study also compared the urine of e-cigarette users to that of non-smokers. Urine samples were examined for five substances that are known to cause bladder that can be found in traditional cigarettes or in common solvents believed to be used in some e-cigarette liquids. The people tested were mostly male with an average age of 39 years old. The non-smokers had abstained from traditional cigarettes for at least 6 months before the test.
Results showed that the urine from 92% of e-cigarette users tested positive for two of the five carcinogenic compounds. Further study is needed to be sure of the link between e-cigarettes bladder cancer.
