6. Smoking: The Leading Preventable Cause

Save

Cigarette smoking is the leading preventable cause of bladder cancer, accounting for nearly 50% of all diagnosed cases, per the American Urological Association. Harmful chemicals in tobacco pass through the kidneys into the bladder, damaging the cells and leading to mutation over time. Smokers are three to four times more likely to develop bladder cancer compared to non-smokers. The best prevention is cessation. Many health plans now include tobacco cessation programs and annual screening coverage for at-risk individuals. Quitting smoking doesn’t just reduce cancer risk—it also lowers life insurance premiums, healthcare costs, and improves long-term survival. If you smoke and experience urinary changes, speak with a healthcare provider about cancer screening right away.
