Don't waste your time with M****tech. They drowned you in quesitonable "research", but their product is little more than overpriced sugar. I had one friend on MT and yes, she thought she felt better too, but the product had no effect on her outcome. She died as expected.
I recomend the Kelley/Gonzales protocol. I also suggest you get a Moss report on bladder cancer so that you can better understand the disease and treatments (both natural and alternative).
A good first start for your dad would be to read "A Cancer Battle Plan". You can find it at Amazon.
You can not fight your dad's cancer, nor can the oncologist. The fight is your Dad's. He has to be 100% commited to the fight, and he needs to be 100% engaged. He needs to get educated, and make treatment decisions fast. I speak from my own experience.
