Microwave ablation is a new tumor ablation technique using electromagnetic waves to heat and destroy cancer cells. This method offers advantages over older technologies, showing promise for various cancers.

Area of Science:

  • Oncology
  • Medical Physics
  • Surgical Technology

Background:

  • Tumor ablation is a crucial cancer treatment modality.
  • Existing thermoablative technologies have limitations.
  • Microwave ablation represents a recent advancement in tumor ablation.

Purpose of the Study:

  • To introduce microwave ablation as a novel tumor ablation technique.
  • To describe the mechanism and advantages of microwave ablation.
  • To highlight the potential applications and future of microwave ablation in oncology.

Main Methods:

  • Utilizes a thin microwave antenna (14.5-gauge) placed directly into the tumor under imaging guidance.
  • A microwave generator emits electromagnetic waves to agitate water molecules in tissue.
