Breast+Cancer+Genetics

__Transmission__ Most breast cancer related cases are not inherited. These cancers are created with genetic changes that occur only in breast cancer cells (somatic mutations) and occur throughout a person's lifetime. In hereditary breast cancer, depending on the gene involved, effects the way that cancer risk is inherited. People who inherit an increases risk of cancer, do not always inherit the disease itself. Not all people who inherit the mutations in certain genes will get the cancer.
