Thanks Kelly for your response and sending through the link to the study. It certainly reads a more positive result than I was lead to believe and I will now follow it up with my oncologist. There is always an unknown regarding residual cancer. I was told the chance of my cancer returning was 30 to 40% as it was locally advanced. To me I have greater odds of it not returning then it returning.
I had had a breast screen 4 months before I found my lump so either the cancer developed and grew after the screen or the screening didn’t pick it up.
In terms of whether you go ahead and get a mastectomy is not an easy decision but it’s a decision you need to feel right about and have no regrets no matter the outcome......no I should have or shouldn’t haves. There are no certainties with cancer so go with what gives you peace of mind.
I wish you well.
