My 71 year old father had a heart attack a week ago. He was being treated in a smaller town. The morning he was to be transported to a larger hospital for a heart cath, he started urinating blood and large clots. Long story short, an ultra sound was performed along with an examination. Only to find a tumor in the bladder. The same thing happened to him 3 years ago. After the cath with a stint implanted in his heart he was examined be another uroligist. My mother was to call today to make an appointment. I know nothing about bladder cancer, what are the chances that he has been walking around with this for at least three years? Anyone know what we are looking at? I am very anxious and confused.
