I keep reading post where folks have cut back or stopped their coffee usage having bladder cancer. Have T-1 High Grade 3 years now with 4 TURBTS & BCG/GEMZAR and no one at doctor5s warned me away from drinking coffee. What is logic on this?
Being a coffee addict, and having been told by one Doc to stop, I went hunting for support.

"The final protective measure is to drink more fluid. It seems intuitive that a high urine volume will dilute toxins in the urine and increase voiding frequency, both of which should protect the vulnerable bladder cells from carcinogens. But intuition can be misleading, and two small European studies reported mixed findings: French investigators did not demonstrate any benefit from a high fluid intake, but Spanish scientists reported that coffee appeared protective.
A large American study, however, was more optimistic. A 1999 Harvard study of 47,909 male health professionals showed that dilution may be a solution to the bladder cancer conundrum. All the men were free of cancer when the study began in 1986. Over the next 10 years, the researchers kept track of each man’s consumption of 22 different types of beverages as well as the occurrence of bladder cancers.
When the results were analyzed, the men who drank the most (averaging about 2 quarts a day) were 49% less likely to develop bladder cancer than the men who drank the least (averaging less than 1 quarts per day).
Although water was particularly beneficial, all types of beverages contributed to protection, including alcoholic and caffeinated beverages, which had been cited as possible risk factors in some earlier studies. "
A longer discussion, less directly science based, from the UK adds some interesting background.

"As you may have already read in the news, the International Agency for Research on Cancer (IARC), a group of international cancer experts convened by the World Health Organization, has just concluded that there’s no strong evidence that coffee increases your chances of cancer (something that they’ve mooted in the past).
But there may also be some other good news for those of us who are coffee drinkers: there’s also some emerging evidence that coffee could in fact reduce the risk of certain cancers."
