Met with the oncologist today to go over the CT scan from my trip to the ER a couple days ago. It turns out the radiologist at the hospital wasn't as inept as I'd hoped, and I really do have a growth on the outside my bladder. Most likely this is a return of my bladder cancer, but a biopsy will confirm. I'm also being tested for Chromogranin A to check for neuroendocrine prostate cancer.
If this is bladder cancer, it should be curable with chemotherapy followed by surgery. Surgery would remove both the bladder and the prostate. The chemo would also theoretically attack the prostate cancer and beat it back a little further. So as much as I'm upset at the thought of losing my bladder, there is the bright side that it may get more prostate cancer out of my body which is a good thing in the long run.
My body refuses to follow any rules. My PSA screening tests didn't detect any cancer until I was metastatic. Now my bladder cancer grows on the outside where it can't be seen in a routine cystoscopy. At this rate, someday I'll find out that I actually died back in 1993 and some cancer has been animating my corpse ever since
