Sequoia, by "my high estrogen count" I meant the ER biomarker on my tumor pathology report was high. 98% of the cancer cells analyzed had estrogen receptors, which was termed "strong". This indicated that my tumor was sensitive to estrogen and that an anti-estrogen adjuvant treatment would be standard care, either by blocking estrogen from binding with the receptor, as with tamoxifen, or by reducing the amount of estrogen in the bloodstream with an inhibitor that prevents the enzyme aromatase from converting androgens to estrogen. Aromatase is found in the adrenal glands, fat, breasts, brain, and muscles. It seems logical that the higher the ER+ percentage, the higher the potential effectiveness of an estrogen blocker in lowering recurrence risk. I have never had my actual blood estrogen level measured.
