Mutations in BRCA genes, specifically BRCA1 and BRCA2, are most notably linked to an increased risk of breast and ovarian cancers. These genes are responsible for repairing DNA breaks, and when they are mutated, the body's ability to maintain genomic stability is compromised. As a result, individuals with BRCA mutations have a significantly higher risk of developing these types of cancers.

Breast cancer is particularly affected because BRCA gene mutations are found in a substantial percentage of hereditary breast cancer cases. Additionally, mutations in these genes contribute to a higher risk of ovarian cancer, making this connection crucial for understanding genetic predispositions in affected individuals and guiding preventive measures and screenings.

The other options, while they might involve other significant genetic factors or lifestyle influences, are not primarily associated with BRCA gene mutations, emphasizing that the correct answer accurately reflects the established link between BRCA mutations and breast and ovarian cancers.
