International Study Finds Effective, Less Toxic Way to Treat Brain Tumors I love this type of research. They took into account the patient's quality of life as well as survival time to determine that for 1 to 3 brain metastases, stereotactic radiosurgery is better used alone rather than in combination with whole brain radiation. The survival times were about the same either way, but quality of life was better with radiosurgery alone. Not to mention a lot cheaper and more convenient.
