Just diagnosed with Invasive Mucinous Carcinoma

Thanks @kmakm and @Lisa1407 for your words of encouragement.  Control is a difficult one to give up but I pray that I found this early enough and the surgeons are skilled.  
One question, the surgeon was talking about the quadrant that would be removed during the lumpectomy.  My brain says a quadrant means one quarter.  Should I be asking about options of reconstructive or does this type of surgery not really require this?
