I had my bladder scraped twice and was treated with BCG. The cancer reoccurred one and one-half years after my original diagnosis. The biopsy showed it wasn’t invasive, however I chose to have my bladder removed. During surgery it was determined that it was invasive, however, doctors felt confident they removed all cancer. Later cancer showed up in lymph nodes in my abdomen. Said no cure, but doctors felt good chance chemotherapy for four months and then immunotherapy had a good chance of helping. Spent two years on Keytruda after chemotherapy. PET scan this past June showed no signs of cancer. Stopped treatment based on this news. Just had a scan this September and all clear. I don’t know what this means for you, but I believe Keytruda with God’s blessing was the answer for me.
