MWA, as a minimally invasive technique, has demonstrated safety and efficacy in the treatment of BTN, low-risk PTMC, and lymph node metastases (LNM). MWA is associated with faster treatment times and the ability to create a larger, more uniform ablation zone, making it particularly advantageous for nodules located near blood vessels. Nonetheless, additional comprehensive studies with long-term follow-up are necessary in the Latin American population to further validate and expand the application of this therapy, particularly in cases of PTMC and LNM.
