This document summarizes a study on the prevalence of cancer-associated genes in breast cancer patients in southern Assam, India. The study surveyed and collected samples from hospitals to analyze the tissues of breast cancer patients through immunohistochemistry and gene amplification. Three mutations - 185delAG, 1014delGT, and 3889delAG - were identified in the BRCA1 gene in southern Assam patients. The mutations have been reported in diverse ethnic populations and are associated with increased risk of breast cancer. Further analysis of patient samples and genes is needed to understand the breast cancer risk factors in the region.
