Hi Rach, 

usually cases get discussed in a multi discipline meeting in which your case gets reviewed by several specialists

surgeons,oncologist. Nurse, physio etc etc.

They discuss history, results grade location, surgery treatment etc etc.

This joint decision will be decided the best outcome, regarding surgery and treatment plan. Which should have been explained and asked your overall opinion.  I've been reading up on some info (only via google tho) Surgeons like to more serve healthy breast tissue and lots of studies have been done into risk of lumpectomy v's mastectomy outcome.

You could ask for a discussion with your breast care nurse. They are often guided by MDT outcome and maybe could give you some more answers to your questions.

However the ultimate deduction is yours.

Best of luck either way ;)
