The cystoscopy is normally done before a TURBS (Surgery to remove a tumor).
The scoping (cystoscopy) is to show the Urologist where the tumor is located, how many there are, how big they are,and how to go about the task of removing them. You are numbed up and it only takes a few minuets in the office to do it. No big deal, I do it every three months.
The TURBS (Transurethral Resection Bladder Surgery) is where they operate on you in a hospital. They put you under and perform the surgery. Then you go to recovery. This is a big deal, but not the worst thing to do.
The tumor is then sent to a pathologist to be tested for cancer. Not all tumors are cancerous!!! Only a pathologist can tell if its cancerous or not.
The same tool is used in both procedures, but they do not remove any thing during the cystoscopy they only look inside. It is the best way of identifying the problem in the bladder.
Like Catherine has said, the sooner the better. But for now it sounds as if you are in good hands. Rest up, enjoy life as best you can, and let us know how things are going along the way.
