I had a second follow up with my surgeon. All was stable, mammo and MRI. I told her about all the physical symptoms and now blood work changing rapidly.
Told her my oncologist said chance of reoccurrence is 50/50, she explained that is the general population my age, my diagnosis etc. She said she would help find out more information. She called me later that day and said she presented my case to oncologists she works with at her hospital and they all thought my case would have a low % rate of reoccurrence.
With all factors considered, I stopped the Letrozole.
My oncologist probably won't be happy but I feel ok with this decision.
