If your tumor is small there is a good chance, there is no lymph node involvement. Your doctor should be doing a Sentinel Node Biopsy (basically blue dye put into the Sentinel 'first node' and if there is no blue dye in it, then it will not have gone into the rest of the lymph nodes). Fingers crossed! (That is done just before your surgery under anesthesia)? Because of the smallness of my tumor there was no need to go the Chemo route. Just a choice between radiation and Anastrozole Therapy which is one of three Estrogen Blockers. Best of luck and the small tumor is a very good start, so try not to worry too much.
