It doesn't however change the statistical facts about the success rates of standard treatment in this type of cancer.
You aren't the kid and the state has no role in it.
It is to be a personal decision. Would I choose Chemo if the success rate was 80%+, sure.
This is his second time. Given my fictitious numbers, I guess he was in the 20% the first time? If the first drug didn't work, and I presume they used the best coctail against it-- the second best coctail might do less. It could do more...
That's why it's a hard decision. The state can bugger off.
