We will list on this site contact information for cancer treatment centers that utilize metronomic chemotherapy as a treatment approach. We do so, without endorsing any provider and encourage you to research their approach and ask about their treatment success rate.


Mark A. Gignac, ND, FABNO

Dr. Gignac has devoted the last 35 years of his life to the study of natural medicines. His formal education began with a seven-year tutelage under Alma R. Hutchens, author of “Indian Herbology of North America.” He went on to earn his undergraduate degree in Nutritional Biochemistry from the University of Ottawa, Canada, and he completed one year of graduate studies in nutrition and human physiology at the University of Windsor before leaving to begin his studies in Naturopathic Medicine.

Dr. Gignac received his doctorate in naturopathic medicine from Bastyr University in 1992 and his master’s degree in Acupuncture and Chinese Medicine in 1996. In early 2006, Dr. Gignac was among a very small group nationally, and only one of two naturopathic physicians in the State of Washington to pass the national board exam for certification as a Fellow of the American Board of Naturopathic Oncology (FABNO)

During his medical studies at Bastyr, he also worked for four and half years at Swedish Hospital for the Laboratory of Pathology where he achieved certification as a Certified Phlebotomy Technician with the American Society of Clinical Pathologists. He was also trained as a Clinical Lab and Bone Marrow Biopsy Assistant at Fred Hutch Cancer Research Center where he was employed for two additional years.

In addition to providing guidance and support to his many patients, Dr. Gignac served as the Director of Integrative Medicine at Seattle Cancer Treatment and Wellness Center for 17 years – the first fully integrated Oncology practice in the State of Washington. During that time, he and Dr. Chen worked together on-site and in real-time providing integrative and innovative cancer treatment options to their mutual patients.

Dr. Gignac has a passion for teaching and education. After graduating from Bastyr, he developed the course curriculum and taught the History of Medicine and Naturopathic Philosophy to Bastyr medical students. Since then, he has continued as a guest lecturer and part time faculty member. Dr. Gignac has been featured many times on Seattle area television and radio shows. In addition, he continues to deliver talks to local groups and speak at national medical conferences on naturopathic approaches to cancer treatment and management.

Because of his deep interest in Mind-Body Medicine and the spiritual and healing practices of indigenous peoples, for the past 16 years Dr. Gignac has travelled extensively to the Brazilian Amazon to further his education.

Dr. Gignac is a member in good standing of the following professional organizations:

Washington Association of Naturopathic Physicians (WANP)

American Association of Naturopathic Physicians (AANP)

Oncology Association of Naturopathic Physicians (OncANP)

Society for Integrative Oncology (SIO)
