Gene mutations in breast cancer can be inherited from which parent?

The correct answer highlights that gene mutations associated with breast cancer can be inherited from both parents. This underscores the understanding that hereditary breast and ovarian cancer syndrome (HBOC) can result from mutations in genes like BRCA1 and BRCA2. These mutations can be passed down through either the maternal or paternal lineage.

Each parent contributes half of the genetic material to their offspring, meaning that mutations can arise from either side of the family. When a specific gene mutation is present, it increases the risk of developing breast cancer and potentially other cancers, regardless of whether it is inherited from the mother or the father. This emphasizes the importance of considering a comprehensive family history from both sides when assessing inherited risks for breast cancer.

Understanding that genetic predispositions can come from either parent is crucial for effective genetic counseling and risk assessment for individuals with a family history of breast cancer. This knowledge can inform screening decisions and preventive measures for patients and their relatives.
