Percutaneous Cryoablation of Low-risk Early Breast Cancer
Expand the current evidence base regarding percutaneous cryoablation of early-stage, low-risk breast tumors, integrated into the standard therapeutic pathway with well-defined follow-up data, as well as data on quality of life. Demonstrate, therefore, that the use of percutaneous cryoablation in the treatment of low-risk breast carcinoma is not inferior to surgery when combined with adjuvant radiotherapy and chemotherapy (when necessary). The hypothesis is that cryoablation, being simple and oncologically effective, ensures a better quality of life for the patient (reduced morbidity, no need for general anesthesia, improved cosmetic outcomes) and consequently has a lesser psychological impact, as well as a better cost-benefit ratio compared to the standard surgical approach.
