Hi, my son is 40 yrs. old has cerebral palsy, and a G-tube, last year he was diagnosed with bladder cancer and today he went for the yearly check up and surprise, he has bladder cancer again, I should have asked the doctor what could possibly be the cause, but I was a little upset and tried not to let me son see me cry. I just wanted to get out of there. I forgot to ask what kind it was and why is it re- occurring. Can you answer my question? what kind it is, because to me it looks like coli flour, are correl reef, .
