Hello,
it is a very worrying time especially having to face it all again. My situation is different because I had my surgery first and then chemo. I was given the option of lumpectomy or mastectomy. I chose masectomy as I wanted to be sure that everything was taken the first time. Every person is different and every treatment is individual. I'm sure your medical team has your best interest at heart and need to reassess your situation before recommending further treatment. Talk to your breast nurse for reassurance.
All the the best for your future journey.
love and hugs Bev
