From the above link
Annually, over 80,000 individuals in the U.S. receive a bladder cancer diagnosis.
The 800,000 are patients who have had a diagnosis, undergone treatment and are being monitored for any recurrence.
This 800,000 is added to each year by 80,000 and subtracted by around the same number due to full clearance from the effects.
Given the age bracket some will pass on as well from other causes.
