My husband has non-invasive bladder cancer. He has been doing it for 18 months. In that time period he has had three reoccurring tumors. He does not qualify for bladder removal and building a new one because of his current health issues and weight. After this last surgery to remove tumor my husband had two options, so he chose to start back on BCG treatments. He just had his first treatment of six for the beginning of 6 treatments. We’ Experienced a first this time. After emptying his bladder of treatment it was bedtime. At night he uses a urinal and the next morning it was full of tissue-flesh colored that sank to the bottom of bottle. He has not complained of discomfort or pain when urinating. He did have a brief spell of very low abdomen pain about 20 minutes in between first and second release of BCG. We’ve dealt with blood clots but never this fleshy stuff. Should we be concerned? Oh he is diagnosed with T1 Highly aggressive bladder cancer. Any answers or suggestions as to what it would be will be appreciated.
