Sorry to hear. Maybe your brother needs to speak with a counselor, therapist or other type of intervention to help. He is too young to give up. I wonder if he was always against conventional medicine, going the alterative route with foods, treatments or is just recently he is seeking a snake oil to cure him, although he used conventional treatment to get tested, and trust their diagnosis, doesn't make sense. You brother may just be fearfull. I know I was. At one of our SPOHNC support group meetings, a couple attended to hear other fighters thoughts on treatments. The gentlemen had BOT cancer, in his 60's, and was just juicing, eating a healthy diet to cure himself. They were also going to attend a tumor board meeting. I think he wound up having radiation. Good luck.
