Jake,
It is real easy to get lost in the new vocabulary once the doctor says "You have cancer". Been there. Some doctors spend little to no time in patient education unless pushed for answers to well formed questions.
We each need to become our own advocates - making a lists of ALL the questions we have and ALL the fears the cancer diagnosis brought us. We need to ask questions and demand understandable responses from our care team.
Linked below is a site from which you can download a copy of an AUA (American Urological Assn.) guide for non-invasive bladder cancer. while not an extensive document, it can help understand the vocabulary and options for dealing with early stage bladder cancer. This guide may be helpful for discussing options with your doctor, as well as reaching a full understanding of the plan(s) and reason(s) for a suggested course of treatment.
Best
Jack
