Lumpectomy tomorrow - lobular cancer and so scared

Thank you for your reply and advice @AllyJay.  It is all just so confusing, but I do feel like a step has been missed.  My tumour wasn't detected on my mammogram in Feb this year (or wasn't there?) and only picked up by accident on a breast ultrasound, otherwise I would be none the wiser.  Very scary to think I would have easily gone on longer until it got to who knows where.  so that's the main reasoning for I want everything checked, gone over with a fine tooth comb.  I cannot understand his reasoning to not getting it done, why would a surgeon not want to do it?.  I will find out more this afternoon. Thanks again for your reply.  Off to try to drink a cup of tea....cannot eat and cannot concentrate today.  Trying times hey.
