Yep, Mayo is a great move. After choosing the medical team the only other thing your sister can control is her attitude and nutrition. Everything else is in the hands of how her body responds to treatment.

I would recommend these support forums for your sister or her caregivers as the experience of those that share on these forums is invaluable. Knowledge is power and the only thing we have when it comes to getting through this experience. Strength in numbers.

The survivors on these forums are a testament to the fact that cancer, even late stage metastisized cancer isn't necessarily a death sentence.

Good luck
