<s>[INST] my father is diagnosed with bladder cancer 4 months ago, he refused to take bladder out or any treatment. he was told 10-11 months to live. he has continued to urinate blood and now it is everytime he urinates and he said it is alot of blood. how long can he bleed before something happens to him? [/INST] Blood in urine is one of the presenting symptoms of bladder cancer. This is common because the tumor is like a raw surface that can bleed spontaneously or with the passage of urine over it. It is not smooth like the rest of the bladder. I am afraid to say but with no treatment and with the blood that he is loosing not being replaced he will not even last the predicted 10-11 months. He will have a massive bleed someday and expire that very day. There are other options besides getting the bladder removed. This includes radiotherapy to the bladder area. This will stop the bleeding and also have a certain chance of cure. I think you should counsel your father about it. It is a painless procedure. </s>
