Advances in Local Ablative Techniques for Breast Cancer

Breast cancer, the most prevalent malignancy in women, has witnessed a paradigm shift in its management over the years. From the historically predominant mastectomies, which often led to significant physical and psychological morbidity, the focus has shifted to breast-conserving surgery and minimally invasive ablative techniques. This chapter provides a comprehensive review of the various ablative modalities available for breast cancer management, emphasizing their mechanisms, indications, efficacy, and potential complications. Ablative techniques characterized by their minimally invasive nature aim to obliterate tumor cells while preserving breast tissue aesthetics. These techniques, including cryoablation, radiofrequency ablation (RFA), high-intensity focused ultrasound (HIFU), microwave ablation (MWA), and laser therapy, aim to obliterate tumor cells while maximizing breast tissue preservation and aesthetic outcomes. Moreover, due to the minimally invasive nature, they are particularly beneficial for patients unfit for traditional surgeries, as most of them can be performed without general anesthesia. However, the non-excisional nature of these procedures raises concerns about the completeness of ablation and oncological safety. Accurate imaging guidance, primarily ultrasound and magnetic resonance imaging (MRI), is paramount for the precision of these techniques. The chapter also delves into the role of ablative surgery in palliative settings, highlighting its potential in symptom alleviation and prevention of disease-related complications. As the field of breast cancer surgery continues to evolve, these ablative techniques, backed by technological advancements and interdisciplinary research, promise to play an increasingly significant role in personalized patient care.
