On 1/3/2000 my Father was diagnosed with a Glioblastoma Multiforme on the right side of the brain adjacent to the motor strip. Were told this location is inoperable. The tumor is the size of a walnut (don't know centimeters). He already is experiencing great fatigue and much loss of use of the left leg. We are questioning if radiation therapy is worthwhile? What results might be expected? What side effects? What quality of life is there with and without the radiation treatments? What about length of life with and without the radiation?
