Breast Cancer Biology, Staging, and Treatment Algorithm

Episode Description (aligned to your script)This episode provides a comprehensive review of breast cancer biology, risk factors, diagnosis, staging, and surgical decision-making, forming the foundation for modern breast reconstruction. Topics include genetic mutations (BRCA, PALB2, TP53), hormonal risk factors, and the role of estrogen in tumor development.The episode reviews the triple assessment (clinical exam, imaging, and biopsy), including key imaging principles such as BI-RADS classification, ultrasound features of malignancy, and the role of MRI in high-risk patients.Pathologic distinctions are emphasized, including LCIS vs DCIS, invasive ductal carcinoma (IDC), invasive lobular carcinoma (ILC), and aggressive subtypes such as inflammatory breast cancer and Paget’s disease. Molecular classification is also reviewed, including ER, PR, HER2, Luminal A/B, HER2-enriched, and triple-negative breast cancer, with implications for systemic therapy.Surgical management is discussed in depth, including breast-conserving therapy (BCT), mastectomy types, and margin principles, as well as axillary management with sentinel lymph node biopsy (SLNB) and the impact of the ACOSOG Z0011 trial.The episode also reviews systemic therapies including chemotherapy, endocrine therapy, HER2-targeted therapy, and radiation, with emphasis on timing (neoadjuvant vs adjuvant) and biologic rationale.Part of Dr. Lara’s Plastic Surgery Compendium — a surgeon-level audio reference built from primary textbooks and surgical literature.
