microinvasion suspected

Hi Dear - I had the unfortunate experience of being given the "all-clear" from my initial pathology report. Meaning only low and intermediate DCIS; no invasion. Very unhappily, a few days later that was amended to include a microinvasion. Apparently the surgeon had asked the pathologist for a fast report, though I had not asked for one, and one slide was still outstanding. Still; the point is this. My information (and I checked) told me that a micro within DCIS, especially if the borders away from the micro are good, is no reason to have an Mx as opposed to a Lx, just because of the micro. Lumpectomy with radiation is as good as mastectomy in many/most cases, if the DCIS is confined to a relatively small area. You do not get rid of the possible nasty implications from a micro by taking your whole breast off. You just don't. And, really, depending on the specific markers, a micro does not put you in very much more danger than just DCIS. As they thought I only had DCIS and nothing more, I was not given a sentinel node biopsy upon lumpectomy. With a micro of invasive cancer, nodal involvement is remotely possible (I was told one in 20, though neither my MO nor my BS suggested I do the SNB when a micro was discovered)). Very rare. I did not have the node biopsy, though, if you do have a micro, it is still the usual standard of care to have it done. I was comfortable not.
