Ok, so based on your diagnosis being Grade 2, Stage 1, Chemo is definitely not a given, so there are other factors as you say, I'm thinking the Her2- has something to do with it also in terms of treatment. The gene test cost me $800 because I didnt have a strong enough history! Ridiculous but have had BC twice!!!! So I think it would be worthwhile for you to do absolutely moving forward in terms of knowing treatment. I'd get your Surgeon to do an urgent referral thats what mine did, though took months to get in here in Melbourne. I had granddads on both sides with Prostate cancer and I didnt qualify Scorpion Queen. uuugh
I also felt the same way about Chemo as you do!! I can say, I dont believe anything will happen to you at all, like everything there are risks! I was so against it, but I did it in the end and am 9 months post chemo...whilst very hard and I was so ill through it, I dont question If I could have done more you know? and I got through it!!!
My lymph nodes were clear, so as you say because there was something detected in yours is another reason they suggest. Its a tough decision and only one you can make as to what sits with you, hugs Melinda xo
