Episode Clinical Challenges in Breast Surgery: Managing Breast Cancer Risk - From Assessment to Interventions
Breast cancer risk varies widely across patients, and surgeons play a central role in recognizing elevated risk and guiding appropriate management. In this episode, we review the spectrum of breast cancer risk and discuss practical strategies for risk assessment and risk reduction. We’ll cover surveillance, lifestyle interventions, risk-reducing medications, high-risk breast lesions, and prophylactic surgery—with an emphasis on translating the available evidence into individualized clinical care.

Learning Objectives:
• Identify major modifiable and nonmodifiable breast cancer risk factors, including genetic predisposition, family history, breast density, high-risk lesions, prior chest radiation, and lifestyle factors. • Select and interpret commonly used breast cancer risk-assessment tools—including the Gail, Tyrer-Cuzick, and BCSC models—while recognizing their important limitations. • Recommend appropriate risk-management strategies based on a patient’s risk level, including enhanced surveillance, lifestyle interventions, genetic evaluation, and endocrine risk-reducing therapy. • Explain the indications, benefits, limitations, and tradeoffs of managing high-risk breast lesions and pursuing risk-reducing surgery, including bilateral mastectomy and salpingo-oophorectomy.
