Discussion about surgery with Surgeon

HiRSVP​ I am sorry to know you’ve had this diagnosis. I had a “choice”— technically - my breast surgeon’s recommendation was for me to have breast conserving surgery/lumpectomy. Similar toMoomincorn​’s experience my surgeon’s recommendation was based on her assessment of a range of factors after she had the diagnostic information.
My surgeon and my oncologist recommended that I start 6 cycles of targeted chemotherapy prior to my surgery (Neoadjuvant treatment), as this would shrink the tumour size (it did shrink from 3.8 cm to <1 cm)  reducing the quantity of breast tissue she would need to cut out.
It might depend on your presentation and cancer type - I had HER2 positive and hormone positive breast cancers (triple positive) which has a very targeted chemotherapy and immunotherapy treatment. The outcome was that my surgery was very smooth and 3 years on from I have no evidence of disease. 
It’s hard to know if it’s the lumpectomy or the radiation but although I had a speedy recovery after surgery the breast remains sensitive and there’s a little bit of tenderness. The mammogram technician said to think of it like having a suitcase packed differently with parts of the breast contents packed back after surgery.
I didn’t but perhaps it would be useful to inquire about a genetic test in case that has interesting insights. 
I don’t regret my choice to go with the recommendation. 
All the very best!!
