Microwave ablation

Targeted microwave energy that heats and destroys cancer cells.

What it is

Microwave ablation is a minimally invasive procedure that uses high-frequency microwave energy to heat and destroy cancer cells in specific organs, such as the liver, lung, and kidney. This heat is generated by inserting a thin antenna into the tumor through the skin, under the guidance of imaging techniques like CT or ultrasound.

What research shows

Studies suggest that microwave ablation is effective in treating small tumors, with high local control rates and low recurrence rates. However, the evidence is mixed regarding its effectiveness compared to surgical resection, and more research is needed to determine its optimal use in different patient populations. Some studies have also found that microwave ablation can be associated with complications, such as pneumothorax or bleeding.

Current status

Microwave ablation is a treatment option for selected patients with small tumors, particularly those who are poor candidates for surgery. However, its use is limited by the risk of complications and the need for further research to determine its optimal use in different patient populations.
