The pathology report says the histologic type of my tumour is mostly invasive ductal and some ductal in situ present, but in the mid portion of the tumour the invasive component shows some lobular changes. tumor is seen across several blocks and, therefore, the gross size of 1.9x1.5x1.2cm will be used as the official size, stage 1, grade 1, NO, MO no vessel invastion clear margins, architectural pattern solid/cribriform. left breast at 11:00 o'clock. What does across several blocks, some lobular changes, and solid/cribriform mean? Does the pathology report mean the tumour was DCIS with an invasive part? Also, my ultrasound and MRI measured the tumour at 1.3, but the pathology surgical report measures the tumour at 1.9: would the 1.9 be the DCIS portion and the invasive part with additional adipose tissue? Or DCIS and Invasive portion of the tumour together, only? I have read my pathology report and find no percentage that separates DCIS and Invasive ductal carcinoma. I had a lumpectomy, radiation and now Arimidex. How likely is this tumour with no vessel or nodal invasion present, onco type dx score in low recurrence, to metastasis?
