Can you catch cancer from someone else? The risk is expressed both in terms of a percentage and as odds. For example, the risk that a man will develop bladder cancer during his lifetime is 3.83%. This means he has about 1 chance in 26 of developing bladder cancer (100/3.83 = 26.1). Put another way, 1 out of every 26 men in the United States will develop bladder cancer during his lifetime.
