Mark Gignac, N.D., M.S.A.

Mark Gignac has devoted much of his life to the study of natural medicine and the last ten years to specializing in naturopathic cancer care.

His formal education into natural medicine began with a seven-year tutelage under Alma R. Hutchens, author of “Indian Herbology of North America”. He went on to earn a degree in Nutritional Biochemistry from the University of Ottawa, Canada, and pursue graduate studies in nutrition and human physiology at the University of Windsor.

Mark received his doctorate in naturopathic medicine from Bastyr University in 1992 and his master’s degree in acupuncture in 1996. After graduating from Bastyr, he was involved in several research studies on natural medicines with Bastyr and collaborating pharmaceutical companies.

He is currently a guest lecturer and part-time faculty member at the University, focusing on naturopathic oncology, naturopathic philosophy and the history of naturopathic medicine. He has also lectured at numerous conferences around the country on naturopathic approaches to cancer treatment.

Mark has been practicing at Seattle Cancer Treatment and Wellness Center since it was founded in 1997.

“What this clinic has are naturopaths, acupuncturists and social workers who really specialize in cancer care,” says Mark, who is a member of the Oncology Association of Naturopathic Physicians.

Mark’s deep interest in the spiritual aspects of cancer and cancer treatment has him traveling frequently to the Brazilian Amazon to further his study of indigenous healing and spiritual practices.

“To effectively treat cancer, you have to cast as wide of a net as possible,” he says. “That means doing innovative oncology alongside the best in supportive therapies, addressing not just the physical, but the psychological, emotional and spiritual realms as well.”


Paul Reilly, ND, L.Ac

Paul Reilly was one of the founding physicians at Seattle Cancer Treatment and Wellness Center, where he has practiced for more than 10 years.

“This is the only place in the state that really has naturopathic doctors, oncologists and other providers working together on an equal and fully integrated basis,” says Paul, who serves as National Director of Naturopathic Medicine for Cancer Treatment Centers of America, overseeing naturopathic care at all of CTCA’s hospitals.

Paul is one of the authors of “How to Prevent and Treat Cancer with Natural Medicine,” (Riverhead Books, 2002) a highly regarded and practical guide that gives detailed advice on preventing and fighting cancer through diet, nutrition, supplements and complementary therapies.

He also wrote the chapter on naturopathic oncology care in the Textbook of Natural Medicine, and has been published in the Journal of Naturopathic Medicine, Townsend Letter for Doctors and Patients and Health Store News.

“The ultimate cure for cancer will be found by working with nature, not against it,” says Paul, a past board member of the American Association of Naturopathic Physicians.

Paul has been a part-time faculty member at Bastyr University, where he graduated in 1985. He is licensed to practice naturopathic medicine in Washington, Alaska and Oregon, and also holds both national accreditation and state licensure as an acupuncturist.

“Part of our job is to help people filter through the overwhelming amount of information out there and find what’s right for them,” he says. “Our patients tend to be more informed, independent in their thinking, goal oriented and not willing to settle for the same-old, same-old.”

That’s important, says Paul, because “taking part in the decision making process and playing an active role in treatment is in itself therapeutic.”


Heidi K. Lucas, N.D.

Naturopathic oncologist Heidi Lucas is a gentle and accepting guide when it comes to helping patients make healthy diet and lifestyle changes.

Change doesn’t have be hard or unappealing, stresses Heidi, who specializes in nutrition and botanical medicine.

"I work with patients to make the experience educational and enjoyable,” she says. “If they understand the reasons behind the recommendations, they are more inspired to make them part of their daily lives."

With her background in therapeutic yoga and meditation, Heidi also helps patients develop a “personal healing practice” to further boost their vitality and immunity.

Her philosophy when it comes to cancer is to harness as many proven and beneficial therapies as possible. In botanical or herbal medicine, that means combining modern research with traditional uses that have been around for hundreds
of years.

At the same time, she will act as a filter for patients struggling to sift through the overwhelming amount of information on natural and conventional cancer treatments.

“I aspire to help patients come to a decision about their care that they feel good about,” says Heidi, a graduate of Bastyr University.

In addition to her position at Seattle Cancer Treatment and Wellness Center, Heidi guest lecturers at Bastyr and the University of Washington, and is a wellness, yoga and meditation facilitator for Cancer Lifeline in Seattle.

Before pursuing her doctorate in naturopathic medicine, she received a bachelor’s degree in Art History from the American University of Paris, France. She is fluent in both French and Italian. 

Heidi feels honored to work in a team of like-minded professionals with patients who inspire and amaze her daily.
“It’s a real gift,” she says.

In addition to her doctorate, Dr. Lucas holds a bachelor’s degree in Art History from the American University of Paris, France, and is fluent in both French and Italian. She is also a member of the Association of Naturopathic Physicians.
