I am heading into my third round of BCG in a week or so. The only issue I have with BCG is I have urgency and little control of urination for a few days and then in a week or so after the last one I'm back to normal.
I've also had blue light. They did it during the same procedure as a TURBT so I was knocked out.
08/16/16 - TURBT - 1 tumor, T1HG, 7.5 cm x 7.5 cm x 1.8 cm, non-invasive papillary.
BCG treatments (15 rounds total - last March, 2018). As of latest cysto, Dec 10, 2019 - cancer free!
