Thank you for response and related experience. Can you tell me if there is ongoing testing and if so, is that also covered by insurance? I don’t mean to make this all about cost but do not want to start down the path of endless tests/appointments that could mount up. And since my doctor is a two-hour drive each way, I have a lot to consider. No daughters; no grandchildren; one sister age 74 with no history. At age 78 I’m on the fence if it would make sense in my situation.
