Hi, @jusme — I'm so glad that you found this group on Connect and that you reached out.
This study on microinvasive breast carcinoma published in Human Pathology journal, though a few years old now, has some useful information: https://bit.ly/2u7eLWS.
I also found this site with summary information on microinvasive breast carcinoma from authors from some of the National Cancer Institute (NCI)-designated cancer centers, and thought you might be interested: https://bit.ly/2KXNDAI.
Something this summary says is that "Microinvasive breast carcinoma is defined as invasive carcinoma of the breast with no invasive focus measuring more than 1 mm . It is almost always encountered in the setting of ductal carcinoma in situ (DCIS); thus, it is commonly referred to as ductal carcinoma in situ with microinvasion." Jan 16, 2017
I thought, in light of that, that you might like to meet other Connect members who have talked about ductal carcinoma in situ (DCIS), like @rpierro@nonipoppy@lexalaska@cindytapp@yasmine@conny51@azlane. Hoping they can share some of their experiences with DCIS with you, and shed further light on microinvasive breast cancer if this also applies to them or others they know.
You mentioned having a body scan to ensure the cancer has not spread. When do you expect to receive the results, @jusme?
