Genetic breast cancer mutations refer to specific changes or alterations in the DNA sequence of certain genes that are associated with an increased risk of developing breast cancer. These mutations can be inherited from one or both parents or can occur spontaneously in a person's lifetime. There are several genes known to be associated with an increased risk of breast cancer, with BRCA1 and BRCA2 being the most well-known. Mutations in these genes significantly elevate the risk of both breast and ovarian cancers. These genes are involved in repairing damaged DNA and suppressing the growth of tumors. When they have mutations, the normal regulatory functions are disrupted, leading to a higher likelihood of cancer development. Key points about genetic breast cancer mutations include: BRCA1 and BRCA2 Mutations: Mutations in the BRCA1 and BRCA2 genes are the most common genetic cause of hereditary breast cancer. Individuals with these mutations have a significantly increased risk of ...
