Radiofrequency ablation rfa is a type of interstitial hyperthermia that uses radio waves to heat and kill cancer cells in regional hyperthermia various approaches may be used to heat large areas of tissue such as a body cavity organ or limb. Interstitial hyperthermia delivers heat directly to the site of the tumor via brachytherapy catheter the microwave power delivered to the antennas available as an optional kit can be adjusted in amplitude and phase to conform the heating pattern to the tumor. Although interstitial radiation hyperthermia appears promising well controlled trials comparing radiation therapy alone versus combined interstitial radiation hyperthermia are needed whole body heating is a complex labor intensive technique that is difficult to accomplish and clinically impractical. In this explanation of brachytherapy and interstitial hyperthermia dr chong describes the differences between low dose and high dose rates of brachytherapy a special iridium 192 treatment unit used in high dose brachytherapy is designed to reduce the impact on surrounding areas like the rectum . Interstitial microwave hyperthermia is used to treat tumors that are deep within the body such as brain cervical breast prostate and neck tumors this technique allows the tumor to be heated to higher temperatures than external hyperthermia techniques allow
