A child is more likely to develop bladder cancer later in life if he/she is exposed to second-hand smoke or smokes, say European researchers. A child who starts smoking before the age of 15 is three times as likely to suffer from bladder cancer later in life than a child who doesn’t smoke.

You can read about this study in the International Journal of Cancer.

The researchers found that adults who do not smoke, but are exposed to someone else’s smoke at home, have no raised risk of bladder cancer. Children, on the other hand, who are exposed to second hand smoke in the home have a 40% higher risk, compared to children who are not exposed to passive smoking in the home.

In the UK bladder cancer is the fourth most common cancer among men.

(Second hand smoke = Passive smoking = Inhaling the smoke of another smoker, but not smoking yourself)

The scientists looked at information on 429,906 Europeans (European Prospective Investigation of Cancer and Nutrition – EPIC). 633 of these people developed bladder cancer within six years.

The authors of the report concluded that children are more sensitive to carcinogens than adults (carcinogens – agents that cause cancer).

Previous studies had revealed a link between smoking and bladder cancer risk. This is the first study to show a link between raised bladder cancer risk later in life and exposure to second-hand smoke for children.
