I have an inoperable brain tumor; radiation did not help? . Don't know what my options are anymore

More info. What specific kind of brain tumor? Was it a glioblastoma? Did you see a medical oncologist? Some chemotherapy drugs may give you some quality of life if the tumor is sensitive to them. An experimental study may be of great interest to you, depending on what kind of brain tumor you have. See http://tinyurl.com/l84zx9m for details.
