I read that fiber optics are being used to basically cook the tumor. Fiber optics is inserted in a small hole in the brain and the tumor is cooked. Have you heard of this? When do you think this will be an option in the US?
This is a technique called laser assisted thermal ablation. This is available at a handful of institutions around the country. A well-informed neurosurgeon should be able to direct you to an institution in proximity that has this option available.
