A Study to Evaluate the Epidemiology of Estrogen Genotoxicity in Breast Cancer

Overview

About this study

The purpose of this study is to recruit 2000 incident cases of primary breast cancer in order to perform laboratory assays to measure frequencies of genetic polymorphisms for genes that encode enzymes involved in candidate gene pathways, including:  estrogen and catecholestrogen formation, bioactivation and inactivation, cellular proliferation and apoptosis, nuclear factor kappa-beta; to compare genotype frequencies for polymorphisms of genes in breast cancer cases and controls, and to evaluate possible interactions among common polymorphisms in candidate genes.
