Tumors Destroyed by Heat
Researchers used laser ablation to treat kidney and liver tumors in five patients who had no visible tumors present after the procedure. The lasers were guided to the tumors via MRI and destroyed them through heat. Doctors say it will most likely benefit individuals who have very few primary or metastatic tumors in organs that are less than five centimeters in size. The Food and Drug Administration has approved the use of laser ablation to treat any soft tissue tumor, but it is most commonly used to treat brain, spine and prostate tumors. Eric Walser who pioneered this technique at Mayo is very optimistic about this technique and points out that "Laser ablation offers us a way to precisely target and kill tumors without harming the rest of an organ."
