Query: I can't read this.

A loved one bought me this book after my diagnosis. I've been awaiting surgery with a fairly positive attitude - until I started flipping through this book. She says one out of every three women diagnosed with breast cancer will die from it (when I understood the survival rates to be much, much higher). She tells the story of her mom, who was diagnosed with it in the early stages and died of it 5 years later. I'm devastated. All the people I've talked to, all the great stories I've heard, were just undone by one casual flip-through of this book. I just went from 'I can beat this' to feeling like I have one foot in the grave. This is the single last book you should be giving anyone with breast cancer.
