I believe that I've read that only invasive breast cancer of 2mm or more can form blood vessels to spread. Under 2mm, such as in pure microinvasion, theorectically shouldn't be able to spread. I must stress PURE micro-invasion here. I think that rare cases of microinvasive relapse occurs when something is missed in pathology that is more than a micro invasive or when there is an unusal drop mets in surgery. Did you have any lymphatic/vascular invasion?- LVI? Did you have a sentinel node dissection to check for spread as that would be another indicator for relapse risk. If you had a positive node or LVI, you may consider late Hercepetin.Good luck.

WARNKING- double check your pathology. Remember I was misdiagnosed three times by pathologists!!! Twice locally in Elmira, NY's XXXXX's path lab and once by a pathologist at the PRESTIOUS major cancer center in NY city,XXXXX-Kettering. Shocker, isn't it?
