Hi @wfu, welcome to Mayo Clinic Connect, an online community where people can share experiences and ask each other questions about any health issue.
I encourage your family member to contact Mayo Clinic International Services https://www.mayoclinic.org/departments-centers/international
Typically the oncology specialists review medical records to evaluate if they can provide care beyond what your family member is currently being offered before requiring them to travel to Mayo.
How disappointing it must have been for your family to discover the tumor inoperable. Did she have chemo before surgery?
