Dr. Lyday joined Cancer Treatment Centers of America® (CTCA) in 2013 as Director of Gastroenterology and Nutrition Services at our hospital in Newnan, Georgia.

Dr. Lyday specializes in the treatment and management of gastrointestinal and liver cancers. He offers many non-surgical technologies to help determine the stage of disease and to provide therapies when surgery is not an option.

While in private practice, Dr. Lyday developed programs aimed at understanding why cancers occur and how they could be treated more effectively. In 2013, the World Endoscopy Organization granted Dr. Lyday an award for his research on Barrett's esophagus, a disorder in the lining of the esophagus.

"These were small pilot programs but very successful and much appreciated by our patients. However, sustaining these programs in the private-practice world was very challenging," Dr. Lyday says. 

"Fortunately, CTCA's organization is uniquely qualified to provide all the elements I would like to see our patients receive: more time spent between doctor and patient, close communication between physicians, collaboration with local research institutions and academic centers, and finally, a patient-first mentality by all of the providers," Dr. Lyday says. "I can't imagine a better setting to provide high-quality and innovative care for our patients."

Dr. Lyday earned his Doctor of Medicine from the University of North Carolina in Chapel Hill, North Carolina, in 1995. His three-year residency in internal medicine was at Carolinas Medical Center in Charlotte, North Carolina, between 1995 and 1998.

Dr. Lyday's three-year fellowship in gastroenterology was at the University of Nebraska Medical Center in Omaha, Nebraska. He completed the fellowship in 2001. Dr. Lyday was an assistant clinical professor at Emory University School of Medicine in Atlanta from 2002 to 2003.

The American Board of Internal Medicine has certified Dr. Lyday in gastroenterology. In 2010, the National Institutes of Health certified Dr. Lyday as a clinical investigator.

Dr. Lyday was published twice in Digestive Disease Week in 2008 and once in a publication for the Obesity Society's 2009 meeting. His abstracts, in order of publication, were titled:

  • Molecular Pathogenesis of Early Development and Progression of Barrett's Esophagus
  • The Molecular Pathology of Radiofrequency Mucosal Ablation in Barrett's Esophagus
  • Reversal of Decompensated Liver Disease Through Weight Management Program Utilizing Calorie Restriction, Behavior Modification, and Physician Monitoring

In addition, Dr. Lyday was the keynote speaker for the National Weight Management Summit in Las Vegas in 2009. His presentation was titled, "Reversal of Chronic Disease through Multidisciplinary Weight Management Program."

Dr. Lyday is a member of the American College of Gastroenterology, American Society of Gastrointestinal Endoscopy and American Board of Internal Medicine.
