How common is bladder cancer?

More common in men. In 2012, an estimated 73, 510 cases are predicted, with 55, 600 in men and 17, 910 in women. This represents 7% of new cancers in men and is the fourth most common, but not in the top ten for women.
Fairly... There are about 68-70, 000 new cases of bladder cancer each year; and the most common type is transitional cell(from the inner lining of the bladder).
