Destruction/reduction of malignant breast tumor with externally applied focused microwave, including interstitial placement of disposable catheter with combined temperature monitoring probe and microwave focusing sensocatheter under ultrasound thermotherapy guidance

Focused microwave therapy (FMT) is a specialized medical procedure designed for the destruction or reduction of malignant breast tumors. This technique utilizes externally applied focused microwave energy, which is particularly effective due to the unique properties of malignant breast tumor cells. These cells typically contain a higher water content compared to surrounding healthy breast tissue, making them more susceptible to damage from elevated temperatures. FMT can serve as either a primary treatment or an adjunctive therapy, especially for patients who may not be suitable candidates for traditional surgical options such as lumpectomy or mastectomy. The procedure is minimally invasive, often involving the use of local anesthetics to ensure patient comfort. During the treatment, a multiprobe catheter is inserted directly into the tumor under ultrasound guidance, allowing for precise targeting of the tumor. The patient is positioned on a modified stereotactic breast needle biopsy table, where the breast is compressed to facilitate the application of microwave energy. This method not only aims to destroy the tumor but may also enhance the effectiveness of subsequent radiation therapy and chemotherapy by sensitizing the tumor cells. The entire FMT process typically lasts between 20 to 30 minutes, concluding with the removal of the catheter and probes, followed by the application of a sterile dressing to the puncture sites.
