I asked a similar question 7.5 years ago of my URO. He was ia much up to speed in the bladder community. He said bladder cancer for some reason is low on the totem pole, probably as it isn't the hot or "sexy' cancer. Thus very little research $$$ in relation to breast, colon and brain cancers. As Sara Anne mentioned if one had a code I am not sure there are therapies to fight it. The one plus might be if there is a genetic predisposition, the more vigilant you might want to be.
