When is enough, enough?

A friend and I where talking today. We both "have" breast cancer we both have had surgery and gone through chemo (she is still doing chemo) next is radiation. But in both our heads is the question when do you get to say cancer free?  In her mind she knew the moment she believed it was gone. Oddly I had that moment also (obviously a different moment than hers).  A definitive moment that our brains "saw"  we were free ... having said that , when do the medico's say this is it!  This is the end.  I have to wait find out if I have clean margins and heal. Then 6 weeks of radiation (30 treatments) I know... know. .. my journey down this path is coming to a close. My new path (unless something presents itself) will be regaining my good health!  What is that saying "you are in pretty good shape for the shape you are in" lol!  I want to feel good again!  I need to feel good again!  I have walked a mile in another man's shoes (I want mine back)...
