Hi Undecided,
I don't think I've seen anything about lump vs mx. For me I wasn't given an option. I had initial surgery but was then told I would need a mx. I then decided to have Chemo before mx. My reasoning for this was that I had lymph involvement and thought that if the cancer cells had acquired the ability to move to my lymph nodes, they coulwe'll be on the move elsewhere. I wanted to get on to systematic treatment ASAP. Chemo worked very well for me, when I had a mx, there was no evidence of any cancer and nothing more in my nodes.
Good luck with your decision. It's a very diffult one.
