Were you exposed to any of the classic bladder cancer risk factors?

Hello:

I've read a statistic that most people who develop bladder cancer had been long-term smokers, or were exposed to certain chemicals, etc.

Were most of you diagnosed and met one of the classic risk factors?

As I understand from studies, the percentage of people who were diagnosed were broken out thusly:

Smoking (tobacco use): ~50–65%

Occupational/chemical exposures: ~15–25%
Industrial aromatic amines and other carcinogens (e.g., dyes, rubber, leather, paints)

Prior chemotherapy/radiation: < 5%

Genetic predisposition: ~7% or less

Unverified risk factors (e.g. repeated UTIs/inflammation): unknown percentage.
