I think there is a mistake somehow about who wrote this. The book says "Richard Bohannon, M.D.
Past President, American Cancer Society, California Division
Terri Pischoff and Kathy Pakosh"
There is no "Terri P. Wuerthner" anywhere that I see. And a quick Google search of ISBN 9780809228454 repeatedly shows Bohannon, not Wuerthner.
