A minimally invasive cancer treatment can significantly reduce the level of pain experienced by cancer patients with bone metastases, a study has found.

Image-guided radiofrequency ablation (RFA), which can be performed in the outpatient setting, is able to limit the need for strong narcotic pain management, according to the American College of Radiology Imaging Network study.

The study demonstrated that RFA is often used to treat liver, kidney and lung cancer tumours and is also a safe and effective pain management tool for patients with bone metastases.

It be an alternative for patients who previously received radiation therapy and have reached their maximum radiation dose but are still experiencing pain.
