I thought you would pick up on the date, Brian. I often check too, and did, and weigh it from there, and like you said, some info is stil applicable, others evolve. My newest doctor, a radiation oncologist, specializing in HNC, wrote the book, "Head and Neck Cancer, a multidisplinary approach." He chastised me for going all over NYC to be treated lol. He said you have to be treated at one place!
