 PHOENIX (April 14, 2014)—

Brian Schade, Executive Director of Arizona Oncology, today announces the retirement of Kenneth Luk, MD, a well-respected radiation oncologist in Phoenix  for over 20 years.

Dr. Luk is a Fellow of the American College of Radiology and Clinical Professor at the Midwestern University School of Medicine of Glendale, Arizona. Prior to joining Arizona Oncology he was the Chairman of Radiation Oncology Division of City of Hope National Medical Center for a decade, followed by a long tenure as Medical Director of Radiation Oncology and Chairman of Cancer Committee at Banner Thunderbird Medical Center. He also held faculty appointments at UC San Francisco, University of Washington, and UC Irvine.

Dr. Luk is a member of the American Society of Therapeutic Radiology and Oncology and a member of the American Society of Clinical Oncology. He served as the president of the American Endocurietherapy Society and was named “Top Doctor” in Phoenix Magazine multiple times.

His areas of special interest included Intensity-Modulated Radiation Therapy (IMRT), Brachytherapy and treating patients with lung, colon and breast cancers. He published over 60 peer-reviewed papers, abstracts and book chapters throughout his career.

In a letter to his patients, Dr. Luk said, “With a lot of joy, and some sadness, I am writing to let you know of my intention to retire. It has been a great pleasure caring for you and your families over the years. I sincerely appreciate your friendship and loyalty. I wish you continued good health and all the best in the coming years.”

“Arizona Oncology is staffed with some of the most knowledgeable and caring physicians in the country,” he said upon his departure.
With his retirement, Dr, Luk also announced that Dr. Benjamin Slane would be taking over his practice in Phoenix. Dr. Slane is graduate of The University of Iowa at Roy J. and Lucille A. Carver College of Medicine, served his internship at Iowa Methodist Medical Center and completed his residency at The University of Arizona in Tucson. “I am glad to have left my patients in his capable hands,” Dr. Luk added. 

Dr. Luk had a remarkable career as a radiation oncologist and educator. Not only did he help those fighting the battle against cancer, he inspired many physicians including his trainees and colleagues to strive for excellence in their academic and clinical endeavors.

“We thank Dr. Luk for all of his years of service, friendship and loyalty,” said Schade. “We hate to see him leave, but we understand that this chapter of his life most close. We wish him all the best as he embarks on his new journey.”
