Dear Dave,
You should have the tumor removed ASAP, if you haven't already. A pathology report will let you know if it is/was cancerous. If it is then PET scan will determine if any active cancer cells anywhere else in your body. My mother only had her catheter in for a week or so. Once it was removed she was a happy camper! stayed at home basically, left the house a few times with it, very concealable. I hope things are going well for you. Try to relax and keep a positive attitude. Please keep us posted.
