It's so heartening to know this. There is a similar approach to the experimental treatments for bladder cancer (no. 1 in the UK, my mother is not English but has it). The need to strengthen the immune system instead of poisoning ppl with chemo (local chemo did not work for my mom, btw) is genius.
Going through hell is exactly how it feels, a sense of total uselessness and heartwrenching worry. But new and experimental treatments give you the dose of daily hope you need.
