Microwave ablation

What it is

Microwave ablation is a minimally invasive cancer treatment that uses high-frequency microwave energy to heat and kill cancer cells. It is typically used for small tumors in organs such as the liver, lung, and breast.

What research shows

Studies suggest that microwave ablation can achieve good local control of tumors, with recurrence rates ranging from 0-30% depending on the organ and tumor size. Evidence indicates that microwave ablation can be effective for patients with unresectable liver tumors, and may be associated with improved survival rates compared to chemotherapy. However, more research is needed to fully understand its benefits and limitations.

Current status

Microwave ablation is a promising treatment option for patients with small, unresectable tumors in certain organs. However, its use is still limited by a lack of standardization and long-term follow-up data, and more research is needed to determine its optimal role in cancer treatment.
