Hi @Frances54
It would be helpful if we got consistent advice from our medical team, wouldn't it? Sadly that doesn't always happen.
When making these sorts of decisions where the percentages appear small, I think it pays to consider your own personality. None of us are keen on the idea of chemo and many have chosen not to have it when it's been offered. If you are the sort of person who is going to spend the rest of your life stressing 'what if' it's probably best to consider doing it. If you can afford the test, it's a good idea, provided you are likely to take what ever advice it provides.
It's a very tough call to make. I had AC in 2006 and worked right through. I had a recurrence (none of this comes with any guarantee) in 2016 and had TC followed by rads and hormone treatment. it has not been a pleasant experience. You really can not tell what is going to happen so you need to trust the best advice you can get, and ultimately goo with your gut. Good luck. Mxx
