I was 51 at diagnosis. Mine was Her2 positive as well as Estrogen . Another lady I met 15 years older...same size tumor had a different regime from me. I had ACT then herceptin...purely because of my age. My nodes were negative.
They do look at long term survival rates with treatment. The first 5 years all much the same. The next 5 years there is a bit of difference but by 15 years it really does have much varied stats with survival rates. This is significant when you are 37.
ACT is hard but doable. You are stronger than you think. I was a mess the day my chemo started. Cried in the shower beforehand. But I put my smile on and in I went. I didn't want to have any regrets in 2 years of not giving it my best shot of being cured.
You can do it. Many if us here have and thought we couldn't also. X
