When do you start 'counting' the years disease free?

It varies a bit. For those having chemo before surgery, it's probably after surgery. I think most of us would think we are cancer free when there is no evidence of disease, which for many may be after surgery if chemo is to cover possible but not identified cancer cells. I had the same treatment and I hoped I was free after chemo, but to be honest didn't feel like saying so till a year after diagnosis. Whatever you are comfortable with would be my advice!
