Medical Expenses for Cancer Treatment in another State

I was diagnosed with Prostate Cancer.   In October I flew to Arizona from Idaho to meet with the Mayo Clinic regarding Treatment Options.  I spent 2 nights there in a hotel and used Uber as Transportation once there.  It was decided to head down there in November to begin treatment.  I had several preliminary appointments and tests from November through December 2025.  My actual Radiation Treatment began in January and  February of 2026.  We drove down in an RV and have stayed at a RV Park.  In the past we have come down as a Snow Bird usually in late January.  Treatment has finished but we will be staying through March.  That's the Background....

 

Question is What can I deduct as Medical Expense if I itemize expenses over the 7.5%?

 

And.....

 

What does significant mean below?, obviously we did some pleasure and recreational activities in between treatments

  1. There is no significant element of personal pleasure, recreation, or vacation in the travel away from home.

Thanks in advance
