I just got diagnosed with invasive ductal carcinoma grade 2 & DCIS grade2. I am trying to understand pathology report. It says ER/PR+ 100%,.
HER-2neu score uniform, intense membrane staining of more than 30% of tumor cells, score 3, positive.
Ki67 Proliferlation Index favorable <10%, borderline 10-20%, unfavorable, >20%.
What does that mean?
