Hi Karen,
I wanted to share another pathology report resource for ILC from the College of American Pathologists: Understanding a Cancer Diagnosis: Invasive Lobular Carcinoma
It addresses what a pathologist is looking for and how he or she makes a diagnosis.
PJ Hamel wrote a nice overview, which is good starting point for getting a handle on invasive lobular carcinoma.
Also worth reading is this Layperson's Guide to Understanding Your Diagnosis and Pathology Report.
Hope these help.
Sarah
