More than 30 years ago, Dr. Bleker became aware of the largely unknown scientific work of Prof. Dr. Günther Enderlein during a training seminar. Since then, she has been intensively engaged with his publications, as far as they are still accessible today. She is committed to the task of summarizing and disseminating Enderlein's teachings from various sources as concisely as possible; for she believes that we cannot ignore Enderlein's research findings if we want to successfully combat chronic diseases, especially cancer.
