A cooperative working relationship between "allopathic" physicians and "naturalists" is long overdue in my opinion, and my opinion ought to be worth something. I am a physician with 25 years experience in cancer medicine and I have board certifications in internal medicine, medical oncology, hematology, and radiation oncology. Mr. Yance's book is a step in the right direction, and I feel it is a worthwhile reference for any physician who is interested in the nutritional welfare of his patients. The book is far from perfect, however. For example, Mr. Yance overstates the risk of carcinogenesis from therapeutic radiation, presents site-specific side effects such as dry mouth as if they were general effects of radiation, underplays the value and effectiveness of radiation for common adult tumors such as breast cancer, and claims benefit for herbal or nutritional remedies for side effects of cancer treatment even when they have been shown to be ineffective in clinical trials. Administration of vitamin B12 and folate to prevent chemotherapy-induced neuropathy is the most egregious example. At the same time, glutamine is not mentioned for prevention of neuropathy though it is known to be useful, at least for prevention of nerve injury from vinca alkaloids.
Another problem is that much of the nutritional information is too technically advanced for most lay readers. One would have to know more biochemistry than the majority of phyicians to wade through the terminology.
Despite its shortcomings, I think Mr. Yance's book is a valuable resource and would recommend it to my medical colleagues. My advice to the general public is to go to the best source for information about cancer treatments. As a medical and radiation oncologist, I wouldn't try to inform my patients about nutritional therapies, and I sure wouldn't ask a nutritionist their opinion about radiation or chemotherapy. Discuss all the therapeutic issues with your main healthcare provider. If he or she won't discuss herbal, nutritional, and other alternative or complementary modalities, ask for other opinions.
