I read your post and it took me back almost a year ago. I thought I was just having radiation and was a peace with that and then wham we recommend chemo. itwas such a blow but like Robyn my onc explained percentages and I too thought I would give myself what ever chances I could.
Unfortunately I had issues with chemo, it wasn't pleasant but now 12 months post chemo its a blur. Yes it was unpleasant but I managed and most seem to sail through better than I did.
Good luck, I hope that you are like Robyn without too many issues.
