Sorry can't help you with the tumor marker tests, isn't it terrible that I can't remember if they checked me with them. Guess it is a good thing that it has been THAT long ago!!!!!!!! WAHOO....20 years!
I do remember that I had regular blood work taken and it seemed like that went on for a long , long, long, long time. I also have lost track of just how many scans, xrays, etc that I have had taken.
Hope that your back is doing better.
Hugs and God Bless,
