Bladder cancer is the sixth most common cancer in the United States, with an estimated 83,730 adult diagnoses in 2021. Smoking is the greatest risk factor (47% of all cases occur in smokers), followed by advancing age and sex (assigned males are four times more likely to develop bladder cancer than those assigned female). The incidence rate in White people is double that of Black people, but Black people are twice as likely to die from the disease.
