Well, It's a good result.
I got a clear scan and a 1 to 2, out of 5, of 'getting' cancer (again), 1 being the lowest and 5 the highest.
So, if you're interested, I'll have a another blood test in 4 months and 4 months after that.
It's a good result.
Thank you for ALL your supportive comments and practical advice.
My advice? For an MRI, a mild sedative does help, a mask does help, feet first does help, if an option.
