Even though I had an OK experience in having 2 tumors removed in the office, they were very tiny (pinhead size) and I definitely had local anesthetic instilled in the bladder and think I had a mild sedative as well to stay relaxed. My initial tumor two years prior was about the size of yours and removal was done under anesthesia as a hospital outpatient.
You need to talk to the doctor and make other arrangements (maybe another doctor!) if he's talking about burning out a polyp/tumor of that size in the office. Aside from the pain and discomfort of an in-office procedure with no anesthetic
, a polyp/tumor that size needs to be carefully cut out in order to get do decent biopsy, which is very important. Cauterizing damages the tissues and makes biopsy analysis difficult if not impossible.
You mention having a one year cysto, which implies that you've been cancer-free for at least 5 years. Could you tell us a little more about your bladder cancer history? Given that this sounds like a recurrence, it's all the more important to do careful analysis for type, stage and grade as that will determine treatment recommendations.
Best of luck!
