STAGES, ALCOHOLISM AND GENETIC BASIS OF BREAST CANCER

Breast cancer (malignant breast neoplasm) initiate from breast tissue, mostly from the inner lining of milk ducts or the lobules that supply the ducts with milk. Two abnormal genes that involve are: BRCA1 (breast cancer gene one) and BRCA2 (breast cancer gene two). The occupation of the BRCA genes is to renovate cell damage and keep breast cells growing normally. But breast cancer risk increases when abnormal or mutated genes pass from generation to generation.
