I went to my urologist with epididymitis. He found the smallest amount of detectable blood in my urine. On a whim, he sent me to have an IVP (They put dye in your blood and radiologist has a look) He saw a mass on my left kidney. 20 minutes later I knew I had cancer when I saw the blood supply to the mass. That was on Thursday. Tests Friday. Monday he took out my kidney with a grapefruit size stage 3 tumor. There was no margin. Many years later my wife told me the doctor told her that I had a 50/50 chance of living 6 months. That was 1992. Lucky me.
