Detailed explanation-1: -BRCA1 and BRCA2: The most common cause of hereditary breast cancer is an inherited mutation in the BRCA1 or BRCA2 gene. In normal cells, these genes help make proteins that repair damaged DNA. Mutated versions of these genes can lead to abnormal cell growth, which can lead to cancer.
Detailed explanation-2: -Researchers have identified many personal and environmental factors that contribute to a person’s risk of developing breast cancer. These factors include sex, age, ethnic background, a history of previous breast cancer, certain changes in breast tissue, and hormonal and reproductive factors.
Detailed explanation-3: -Genetic testing for hereditary breast and ovarian cancer looks for mutations in the BRCA1 and BRCA2 genes. Your doctor might suggest testing using a multigene panel, which looks for mutations in several genes at the same time, including BRCA1 and BRCA2.
