(
Sighing in relief!)
This story is the perfect example of doctors giving up on a patient for any number of biases (age, other health factors, ability to pay, etc.). I am SO HAPPY for your Mom's sake that you persisted and insisted as you did for the further tests to corroborate that what-turned-out-to-be faulty PET scan.
There were just too many unanswered questions to just throw in the towel. And YOU KNEW IT! Just glad that the answers you got here helped you to get on your feet and move foreward with all the tests and followups. And this after the emotional shock you suffered.
We know you will keep up the tender loving care for your Mom, and what a nice early Mother's Day present you both got.
This news made MY day.
