What type of BC have you got? It's very common now for triple negative to have neoadjuvant chemo (before surgery) as that type gets hit hard by the chemo and can often result in lumpectomy over mastectomy.
Type/size/grade (how fast the cancer is growing) all effects reasoning to do chemo first versus surgery.
Even if you have chemo after surgery, this in theory is going to mop up any remaining cells floating about and is why most of us early BC patients score chemo.
Your friend meant well but sometimes what those around us say can come across really harsh. Comparing cervical cancer treatment to breast cancer is silly. Every different type of cancer has different treatment pathways and unless your friend works in healthcare or has personally dealt with breast cancer they just don't understand unfortunately.
It can get really frustrating trying to explain this to people who keep asking. Until you've made your mind up you can always say you are still evaluating options.
