Really interesting fusion of medical and magical you're exploring here. Cancer-fics aren't really my cup of tea, but you've definitely put an inventive take on it.

I opened my email, saw all those updates from you, and my head exploded. Luckily, happiness revived me. Doesn't sound like Fluttershy will be that lucky.

I mean, 35% is better than...other odds...but still...

Discord's gonna have to face a world without her sooner or later...love the details about Discord's old "favorites" and his worries that his own magic caused Fluttershy's cancer. Poor guy, despite what Twilight said, they, at the least, made it worse.

*snickers* Listerine.

Hmmm, unless, of course, this is set before "Last Problem". Though knowing you that's too easy of a answer. lol Maybe Fluttershy's treatments is why all the Mane 6 have bags under their eyes in the "Last Problem" when no other adults do unless something's going on to cause stress/exhaustion/etc.

Well, sad fic outta the way. Which one to read next...
