@Caseypinto Welcome to you! You really have to be guided by your Specialists in terms of your definitive pathology, it is such a hard decision to make and there really are alot of complexities to it. In 2011 I too was diagnosed with non invasive DCIS high grade, lumpectomy, clear margins and 5.5 weeks of radiation and then Tamoxifen for 4yrs. I did however have a recurrence in 2015 at my yearly checkup, 2.5cm tumor IDC ER+ Stage 2, Grade 3 Aggressive which rendered me mandatory Chemo after another major lumpectomy. As I was big breasted, with no node involvment, lumpectomy was as good as a mastectomy in my case. I was happy with my choices as I went. 14 months after finished chemo, at their recommendation I did a single mastectomy purely due to having had a recurrence and an immediate Diep Flap reconstruction. I was BRCA Gene negative and Genetic Counselors said that a double was unnecessary as did the Specialists as Nikki said, my risk in the right was as general population, they are not related.
My Mum had BC at age 40, they did an immediate single mastectomy and reconstruction and she had NO TREATMENT. She survived 26yrs and they say her Cancer was unrelated to BC.
I have to be honest with you, whilst I'm really ok and happy that I made each decision at the time that was best for me...hindsight is a wonderful thing and you just cannot foresee the road ahead. After 6yrs I am 2 years clear, all treatment done and just waiting for my revision surgery. Yes I have side effects that impact my life but overall I'm in such a great place moving forward and never looking back. My approach in future would be different however, I'd do immediate Mastectomy and no treatment. :) So just do what feels what is right for you, there are no right or wrongs, only what you want and can live with.
