“There are few areas of medicine where the relationship between the mind and body is more compelling than in cancer treatment,” says Dr. Mark Medlin, Psychiatrist at Cancer Treatment Centers of America® (CTCA).

“What makes CTCA® stand out in this regard is that the patient is treated as a whole individual from the very first visit," he adds.

Dr. Medlin earned a bachelor’s degree in chemical engineering from Texas Tech University in 1979. After working as a chemical engineer in Texas and Louisiana for several years, he returned to academia to pursue medicine.

He earned his medical degree from the University of Oklahoma Tulsa Medical College in 1988, and then completed a residency in general psychiatry at Griffin Memorial Hospital (formerly Central State Hospital) in Norman, Oklahoma in 1993.

For the next 15 years, Dr. Medlin served as a psychiatrist at various hospitals and clinics in Oklahoma. He has worked with adult and pediatric patients in both inpatient and outpatient settings, including acute care, crisis intervention and geriatric care. He also served as medical director at large regional hospitals, caring for both adults and adolescents.

Dr. Medlin is a Diplomat of the American Board of Psychiatry and Neurology. He holds a medical license from the State of Oklahoma, and is also licensed by the United States Drug Enforcement Agency.

Dr. Medlin joined CTCA in October 2013, where he provides psychiatric support for patients coping with cancer. “The most important approach is to start where patients are and move to where they want to be,” he says.

As he explains, some patients may believe that feeling depressed or anxious means they are not handling their situation well. “Patients need to understand that they are dealing with extraordinary stress, and it’s important to recognize how that affects them in all aspects of their lives,” he says.

Dr. Medlin works closely with patients at CTCA to help them see how cancer and its treatment can affect one’s state of mind. “I focus on helping patients advocate for themselves and be active participants in leading and directing their own care,” he says.

Patient ratings and comments
