Cardiometabolic risk is a cluster of conditions — including high insulin, cholesterol, and blood sugar — that significantly raise the risk of heart disease and diabetes. Early testing is key to prevention.

Single nucleotide variations (SNVs) in the enzymes that metabolise estrogen can significantly alter breast cancer risk — in some cases by as much as 12-fold when multiple variants combine. In this detailed scientific overview, Jillian Harrington PhD of ZRT Laboratory explains how variations in CYP11A1, CYP19A1 (aromatase), CYP1B1, COMT and MnSOD affect the estrogen metabolism pathway, why catechol estrogens are dangerous, and how methylation testing can reveal individual vulnerability.
