Josef Issels

He wrote a number of books, including an autobiography in 1981, My fight against Cancer, about his understanding of cancer, as well as many scientific articles.

Issels opened his Ringberg Clinic in Bavaria in 1951. As the clinic achieved greater fame, patients from around the world began to seek his treatment. However, other doctors did not approve of his practice, specifically the Bavarian Medical Council, which charged Issels with fraud and manslaughter. After a four-year legal battle, Issels' convictions on all charges were overturned, and his clinic was re-licensed. Issels centers and clinics continue to treat cancer patients around the world, with all types and stages of cancer.

Later, during the Second World War, Issels reportedly petitioned to resign his membership in the Nazi Party when he was ordered to stop treating Jewish patients. His petition was granted, but he was immediately drafted and sent to the Eastern Front as a Wehrmacht combat medic. Captured by the Red Army, Issels spent several years in Soviet prisoner-of-war camps until his release at the end of 1945.

Josef M. Issels (November 21, 1907 – February 11, 1998) was a German physician known for promoting an alternative cancer therapy regimen, the Issels treatment. He claimed to cure cancer patients who had been declared incurable by conventional cancer treatments. During Issels' lifetime, his methods were controversial, and in 1961 he was charged with fraud and manslaughter for allegedly promising fraudulent cancer cures and for the subsequent deaths of patients under his care who refused standard cancer treatment. An initial conviction on the manslaughter charge was overturned in 1964 on the grounds that Issels had genuinely believed that his therapy could cure cancer. Since at least 1972 the Issels treatment is described as unproven, and considered ineffective as a treatment for cancer.

Born in Mönchengladbach in 1907, Issels received his medical degree in 1932 from the University of Würzburg. According to an obituary in the Journal of Alternative and Complementary Medicine, Issels made a name for himself as a young physician several years later by successfully operating in makeshift conditions on an ill passenger aboard a German steamer.
