Unsure about radiation after complete response after chemo & surgery for triple negative bc - Help

Hi there, so sorry you have found yourself in this situation.
I was 31 when diagnosed with her2 positive locally advanced with lymph node involvement. Had complete pathological response and breast conserving surgery followed by radiation. 
I am also a radiation therapist so see lots of breast patients daily with differing pathologies etc. The standard of care is to still have radiation despite complete response as a kind of insurance policy. Plus your young age is a factor so they want to hit it with everything.
Ultimately the decision is yours.
Best wishes xx
