Hereditary cancers, such as those associated with BRCA mutations and Lynch syndrome, highlight the significant role of inherited genetic mutations in cancer risk. BRCA mutations are closely linked to breast and ovarian cancers, while Lynch syndrome predisposes individuals to colorectal and uterine cancers. Genetic screening has become a cornerstone in identifying at-risk individuals, enabling preventive measures like enhanced surveillance or prophylactic surgeries. Emerging therapies, including PARP inhibitors, offer targeted options for mutation carriers. Family-based genetic counseling helps navigate risk management strategies and promotes informed decision-making. Continued research into hereditary cancer pathways fosters the development of innovative prevention and treatment approaches, improving outcomes for affected families.
