Microwave Ablation

Master
Media Component
Content

Microwave ablation is a minimally invasive surgical technique for the treatment of primary and secondary liver tumors. After localizing the tumor with imaging guidance, a thin microwave antenna is placed directly into the tumor. A microwave generates electromagnetic waves that heat water molecules in the tissue producing heat that induces cellular death. Ablation can be performed without surgery or during open or minimally invasive surgery.

Microwave ablation can be considered a safe technique for the treatment of liver tumors.
