Breast tumors mainly include cancer and fibroadenomas. Treatment of these lesions has evolved towards the use of less invasive or minimally invasive techniques. Minimally invasive treatments destroy focal groups of cells using a non-surgical method. It requires less anesthesia, provides better cosmetic results due to minimal scarring, and provides earlier recovery. These techniques include cryoablation, radiofrequency ablation, microwave ablation, high-intensity focused US, laser therapy, vacuum-assisted excision, and irreversible electroporation. Each method involves the use of different mechanisms and applications require special considerations.
