Abstract: 1. INTRODUCTION: Cowden syndrome is a rare autosomal dominant genetic condition associated with mutations in the PTEN gene, which increase susceptibility to multiple neoplasms, particularly breast, thyroid and endometrial cancers. 2. CASE REPORT: A 35-year-old woman carrying a pathogenic PTEN mutation, with a diagnosis of breast cancer and a significant family history of breast and thyroid malignancies. 3. RESULTS: Risk stratification tools, such as QCancer and ASK2ME, demonstrated a markedly elevated cumulative cancer risk, with particular emphasis on breast cancer, for which lifetime risk estimates may reach up to 90%. 4. DISCUSSION: Early detection of germline mutations enables targeted surveillance, preventive interventions, and individualized clinical follow-up, directly contributing to reduced morbidity and mortality. 5. CONCLUSION: Oncogenetics plays a central role in identifying high-risk individuals, providing genetic counseling, and optimizing clinical and preventive management.
