My initial numbers were from a fine needle biopsy (A very small sample of tumor tissue). Once the tumor was taken out and tested , a couple of the numbers were significantly different, My PR %went from 42 to 0 , my KI 67 went from 21-30 to 6-10 . This changed my diagnosis from luminal A to Luminal B. Also , as soon as I found out the fine needle biopsy came back as ER + , I immediately stopped my estrogen replacement therapy which was probably responsible for lowering my KI 67 score … since it was 21 days before the mass was removed
