Dr. Michael Thomas says he joined the staff of Cancer Treatment Centers of America® (CTCA) in Tulsa in 2006 because of the hospital’s commitment to excellence and its collaborative, patient-focused culture. He performs general surgery, oncologic surgery and breast surgery.

“The fact that breast cancer patients see a medical oncologist, a breast surgeon, a radiation oncologist, a plastic surgeon—and their case may be discussed at a breast conference where perhaps 12 to 15 doctors are around the table, reviewing management and treatment? That means that we consider all available options,” Dr. Thomas says.

When performing breast cancer surgery, he works closely with a plastic surgeon to address his patients’ breast reconstruction goals. Trained in the various aspects of general surgery, surgical oncology, as well as breast-conserving lumpectomies, nipple-sparing mastectomy, laparoscopic and robotic surgery, Dr. Thomas says he takes time to get to know his patients on a personal level.

“I say, ‘I’m going to walk with you through the whole process, and we are going to take care of you,’” Dr. Thomas says.

After completing a bachelor’s degree in respiratory care at the University of Central Arkansas, Dr. Thomas earned a medical degree from the University of Arkansas for Medical Sciences in Little Rock. He then completed a residency in general surgery at the University of Kansas School of Medicine in Wichita, where he trained with breast surgeons and helped author a research report on aneurysm repair, published in the Annals of Vascular Surgery. In 2001, he was voted the medical school’s Outstanding Chief Surgical Resident.

Dr. Thomas is board certified in general surgery by the American Board of Surgery and is a Fellow of the American College of Surgeons. He is a member of the American Society of Breast Surgeons, the American Medical Association and the Society of Laparoendoscopic Surgeons.

In addition to caring for patients at CTCA, Dr. Thomas serves as chairman of the Department of Surgery at the Oklahoma State University Center for Health Sciences. He credits his grandmother, a nurse who cared for patients with chronic diseases, with inspiring his passion for medicine. “I look at this not just as a job,” he says. “For me, I look at it as a calling.”

Patient ratings and comments

Star ratings and comments are only available for medical, radiation and gynecologic oncologists. Gynecologic surgical offerings are not included at this time due to a different survey tool required to evaluate these services. CTCA uses a validated Press Ganey® survey, which captures patient experience feedback for the primary oncology services of chemotherapy and radiation therapy. Following industry best practice, star ratings and comments are only published for physicians with a minimum of 30 completed patient surveys.
