That's great that you will have a baseline TSH pre-cancer. I'm glad that Chuck added his testimonial
Fortunately, your pre cancer test will tell you what is the correct TSH level for you. You will probably have to go to an endocrinologist as most GPs and even CCC docs blindly adhere to the lab limits, but any decent endo will know that you want to be back where you were and help you.
Just last night, my wife added her version of Chuck's story as she commented that for the first time in three years, she could snuggle up to me and get warmed instead of chilled. It's a big deal for us and one reason I am going to focus on TSH levels more here on OCF.
Good luck
