Hi @sunrise_sunset, I was in your shoes this time last year, IDC stage 2 grade 3 and 1 lymph node involved. My oncologist strongly recommend chemo because of the high grade, the same treatment you have been recommended. It's a lot to take in, but I found the treatment manageable, and I'm 5 months post chemo now and feeling almost like my old self. Side effects vary from person to person, there is a chat 'struggling through chemo' which might give you an idea of what to expect.
This group has been wonderful for support and just for asking questions, and knowing there are people out there going through the same thing.
All the best with your treatment journey. Katie
