Minimally Invasive Ablation Techniques for Breast Cancer
Summary
Minimally invasive ablation encompasses a suite of image-guided therapies designed to destroy breast tumours in situ, sparing patients the morbidity of conventional surgery. Techniques include cryoablation (the application of extreme cold to induce cell necrosis), radiofrequency ablation (RFA, which uses alternating electric currents to generate heat), microwave ablation (MWA, in which electromagnetic waves produce rapid tissue heating) and high-intensity focused ultrasound (HIFU, delivering acoustic energy to coagulate target tissue). All rely on precise imaging—ultrasound, magnetic resonance or contrast-enhanced mammography—to localise lesions, monitor treatment delivery and assess completeness of ablation. These approaches offer advantages of reduced pain, minimal blood loss, preservation of breast cosmesis and shorter recovery. Emerging evidence highlights immunological sequelae of ablation, in particular the release of tumour neoantigens and enhanced local and systemic immune responses. While patient suitability hinges on tumour size, location and molecular subtype, ongoing refinements in device design, guidance techniques and combinatorial regimens with immunotherapy or targeted agents are expanding indications and improving long-term outcomes. Such therapies promise to transform early-stage management and provide alternative options for those unfit for surgery.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
