My mother's health, part two

As I understand it, there are three main issues with her health:

1. The diagnosis has undergone several revisions, but it's now confirmed she has Goodpasture's Syndrome. This is manageable, though she'll need dialysis from now on.

2. There is a mass in her kidneys, apparently unrelated to the renal failure, and no one knows what it is. There are ways of investigating it, but not without risk.

3. There now seems to be a problem with her heart. She's undergoing a heart catheterization tomorrow morning at 8:00.
