How do you know if treatment worked?
I was first diagnosed with DCIS in 11/2019. Had a lumpectomy 1/2020. First followup mammogram indicated cancer again and I had a second lumpectomy 5/2021 followed by chemo, radiation and IV treatment for HER2+ cancer (2nd lumpectomy indicated HER2+).
I keep asking my oncologist how do I know if this is working and she keeps telling me that I won't know.
This is becoming more and more unacceptable to me. How have you all been sure that your treatment is working? I don't know even know what to ask for but at this point I'm tempted to go to another oncologist. But as all of you with cancer know - it highjacks your life and it's just really hard to get psyched up to spend time making appointments and going elsewhere.
So, please tell me - how did you all know your treatment worked - or didn't?
