Randy\'s tests-why???

Took Randy Friday to get a biopsy to determine the type of terminal cancer he has.Why? It won't change anything,I guess i'm hoping for answers.Answers about how long exactly,how horrific the symptoms will get,how to tell when it's time to let go.Maybe see if Prednisone will help this type of cancer.It helps immensely w/some and makes others worse.Will get biopsy results this week.Just watching him now for any bad signs.Not a fun thing to have to do.But we know the drill by now.
