Well I just heard that she has the type which requires the six months of chemo not the two years. That's got to be good? I didn't even realise there were different sorts. They are to start the treatment immediately.

There are probably hundreds of different kinds of leukaemia known by now, and about as many different outcomes and appropriate kinds of treatment, ranging from "give up, nothing will work" to "no treatment is needed, you'll die of something else decades from now" - and in between, some kinds have very effective new treatments. It would help a lot for somebody to find out which she's got.
