Nope, no blood transfusion recently; no bladder infections. Thanks for all your suggestions and help. I guess I have to think that maybe I'm looking for zebras when the elephant in the living room is the darned bladder cancer.
I just really, really don't want to have to deal with that again. But maybe it's something simple . . . related to the recent tests rather than a return of the cancer. Like perhaps a nick during the cysto a month or so ago left a scab that popped off and caused some minimal bleeding . . . and it doesn't take much blood to look scary. Guess I'll have to investigate further with the uro. Maybe in another week or so . . . or wait and see if it happens again . . . he's just too tired and run down right now to have to deal with anything else.
