That's great news for you guys and for the rest of us hoping for similar good outcomes. I am done BCG and into the cysto's every three months. I go back in early January. I do have one minor issue that I'll write about on open forum.
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, Jun 19, 2019 - cancer free!
Best of luck with your journey. All I can say is my husband has never missed his three month checkups and has done everything the doctors has requested. Our urologist says this is the reason he is where he is today.
