Not an infection.
Not a blood clot.
Not more cancer.
Nothing is wrong with Mom's heart.
They saw shadows at first, but they did more tests, and that's all they were - shadows.
Although...she does have an apparently benign tumor in her brain;
and the cancer in her lungs is starting to grow again, so that means more chemo;
and it's likely the chemo that started her internal bleeding problems in the first place.
But still, I'll take good news when I find it.
There's nothing wrong with her heart.
