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

Radiotherapy will help zap even the tiniest little cancer cell that may be left in your breast (including skin) and your lymph nodes.  I had chemo, then radiotherapy then bilateral mastectomy with reconstruction (my diagnosis was multi-focal).  Radiotherapy is a breeze compared to chemotherapy and surgery.  Yes, it’s a pain having to attend appointments everyday for so many weeks and then sometimes you end up with nasty skin reactions... but it is better to be safe.  They wouldn’t just recommend radiotherapy ‘just because’.  Hope this helps a little.
