Dear shahworld:  The stage of breast cancer depends upon the measurement of the invasive (or infiltrating) breast cancer and the number and location of positive lymph nodes as well as any distant sites of metastasis.  From this report, it is not clear if the "14 reactive axillary lymph nodes" are "reactive" or positive.
