I was diagnosed with "invasive ductal carcinoma of no special type with lobular invasion pattern" (Stage 1, Grade 2, ER+ PR+, HER2 -, Oncotype score 6). I know this thread is about ILC, not IDC, but my question is... What is the difference between ILC and "lobular invasion pattern"? I have found differing descriptions, and I know that the pattern was enough to get the oncologist to prescribe an additional boost at the end of radiation, but I still am unclear as to the difference between this and ILC. Do I have both? Thank you! (and if this is more appropriately addressed in another thread, please let me know - thanks!)
