In 2001 Jürgen H.R. Thomar, who was born in 1938, was diagnosed with prostate cancer. In 2002, after undergoing conventional medical treatment at a university hospital, he was diagnosed with recurrent cancer. After numerous tests and examinations, he was offered a therapy that had not been scientifically documented, so J. Thomar was to become a "guinea pig". Realizing this, the author of the book lost faith in conventional medicine and turned to naturopathy. He found assistance and advice in the book "Natural Treatment of Cancer, Leukemia and Other Seemingly Incurable Diseases" by Rudolf Breuss, a well-known healer, naturopath and folk medicine expert from the city of Bludenz (Austria). R. Breuss, who died in 1990 at the age of 91, developed a remarkably effective treatment method based on therapeutic fasting and consumption of vegetable juices. Using this method, which has already been practiced for decades, many cancer patients manage to regain their health. Undertaking the Breuss cancer cure requires from patients determination, endurance and self-discipline.

Although this method of treatment cannot guarantee complete success, it is viewed as a supportive therapy with prospects in treating a wide variety of cancers. In spring 2004 the author himself completed this course of treatment, which had been repeatedly and successfully used by Breuss; this resulted in complete recovery, which was confirmed by all subsequent tests and examinations.

After completing the course of treatment Jürgen Thomar, as a mark of gratitude to Rudolf Breuss, created the website www.breuss-kur.de, which has generated immense interest worldwide: so far, this site has received over 300,000 visitors. That started Mr. Thomar's literary activity.

Mr. Thomar, with his book “Rudolf Breuss Cancer Cure Correctly Applied”, deserves credit for providing a practical and reader-friendly systemic description of the Breuss treatment, thus developing a guide to the Breuss Cancer Cure. This book should be seen as a fundamental manual to successful application of the Breuss cancer cure. Mr. Thomar is the author of several other books, including: "Heilfasten nach Rudolf Breuss ... einfach genial" ("Rudolf Breuss Fasting Therapy – Simply Ingenious" – in German), "Pratique de la Cure Breuss: Expériences, conseils et recommandations" ("The Practice of the Breuss Cancer Cure: Experience, Advice and Recommendations" – in French), and his autobiography "Das war's" («How it was" - in German) in pocket book size format, covering the same topic of defeating cancer using the Breuss cancer cure.
