The passage is misleading but I think your interpretation is too literal as well. We don't know if she's still live but she's still well within the survival rate (according to Wikipedia). It most definitely improved her quality of life and perhaps that gave her system a boost. We do know that the mind might not be able to cure terminal diseases but it can be a powerful force in making life more manageable (placebo, etc.).
