Lecture Recordings

Note that the "Enzymes and Cancer" lecture was given to an audience of both laypeople and professionals, and provides a broad overview of Dr. Gonzalez's treatment approach. The BoulderFest 2008 lecture was presented to a largely professional audience, and covers the contemporary support for the enzyme approach to cancer. The most comprehensive and detailed recording available is of the seminar "The Enzyme Therapy of Cancer," which covers more technical aspects of the therapy.

On April 18, 2009, Nicholas J. Gonzalez, MD spoke at a seminar sponsored by Nutri-Link LTD and held at the Royal Society of Medicine in London, England. Over several sessions totalling nearly seven hours, he discussed the scientific support for his approach to cancer and other degenerative diseases. He reviewed the history of the enzyme treatment of cancer, dating back to Dr. John Beard, the British embryologist who 100 years ago first suggested that the pancreatic enzyme trypsin represents the body’s main defense against cancer. A reference list and an excerpt (3.8 MB) are available.

Please note: because of problems in the recording process during the seminar, Session 1 has occasional defects in the sound as demonstrated in the excerpt. Session 1 also has some background noise (1.3 MB) due to microphone problems that were corrected after the first 15 minutes, and there are variations in volume at times in most of the lectures. However, the lectures are comprehensible throughout.

The lectures are available as audio CDs, or as a download of five MP3 files representing five sessions. For the downloads, you may purchase the complete set, or you may purchase Session 1 and then return to purchase Sessions 2-5. The audio CDs are only available as a complete set.
