Hi there and welcome to the forum. Sorry to hear about your Dad being diagnosed with bladder cancer. I also have bladder cancer, but it isn't muscle invasive at this point, so I still have my bladder. I have regular cystoscopies and treatments in between and they are keeping an eye on things. I can't answer your question, but I would suggest you post it in the section, "Ask the Nurses" as they are best able to answer anything of a medical nature. You can also phone them during business hours at the number at the bottom of this page, if you live in the UK.
Good luck with it and come back on to the forum and let us know how things go with your Dad. Take care.
