@jewel-ee Must have been good to hear your ki67 was so low! Mine was 18%.
I'm like @"Kiwi Angel", having set out on a course of action I to complete it. But we are all different! I suppose the questions are more or less the same as they were at the start of chemotherapy. The difference is now chemo is a known quantity, as is your quality of life during treatment. Is the short term pain worth the long term gain?
For me what it would come down to is the what ifs. If I did get a recurrence (and I know there are no guarantees no matter how much you throw at it), would I torture myself with the 'what if I'd completed the chemo' question. I know I would so I'd grit my teeth and finish it.
Good luck with your decision. Let us know how you get on. K xox
