@goldengirl2 I realize that I never provided the contact information for Mayo Clinic should you wish to consider getting a second opinion there. Given that you're Canadian, you should contact International Services https://www.mayoclinic.org/departments-centers/international. Here's specific information for Canadians https://www.mayoclinic.org/canada

I believe @bluemeade7 said she is a Mayo patient. She may be able to provide firsthand experience with the cancer center there.
