What kind of cancer, tumor and location ? I've had cancer and I wish your brother the best. Eating well and anti-oxidants help. Be careful and well thought out on your suggestions. From experience I can tell you that the self-ordained healers, herbologists, and holistic gurus wanting to send you to Tijuana for some whack treatment drove me as crazy as the cancer itself. I had UPS waking me up every day with another bottle of Noni Juice, Coral Calcium, healing crystals, or whatever fashionable wonder cure of the moment was sent by a well meaning individual every damn day. It's nice that people care, but when you're sick it gets tiresome to listen to a different jackass every day tell you of a miracle doctor in South America or Zurich. Have him focus on building his own immunity and strengthening his mental resolve.
