A doctor and medical researcher with 30 years of experience, Dr. Seah Lim is the Director of Hematologic Oncology & the Stem Cell Transplant Program at Cancer Treatment Centers of America® (CTCA) at Southwestern Regional Medical Center.

He was drawn to the variety and quality of services offered to patients at CTCA, and the overall atmosphere. “I have never seen so many happy and extremely helpful physicians, nurses and employees at a cancer center,” says Dr. Lim.

Originally from Malaysia, Dr. Lim trained as a physician scientist and hematologist in the United Kingdom. After earning his initial medical degree at Aberdeen University Medical School in Scotland, Dr. Lim served as resident physician and surgeon at various hospitals. He continued his training as a doctor registrar in hematology at Queen Elizabeth Medical Centre in Birmingham, England, Singapore General Hospital, and Addenbrooke’s Hospital in Cambridge, England.

Dr. Lim also completed a research fellowship at Cambridge University in 1993, and then became senior lecturer & consultant hematologist at the University of Wales College of Medicine. In 1995, Dr. Lim began a research laboratory, and conducted studies in hematology alongside treating patients.

Dr. Lim came to the United States in the late 1990s and has held several hospital and academic appointments. He has served as attending physician at academic hospitals and directed hematology and other oncology programs at cancer centers in New York, Texas and Alabama. He established the accredited Amarillo Blood and Marrow Transplant Program at Texas Tech University Health Sciences Center. Dr. Lim joined CTCA in January 2014.

He has been awarded numerous large federal research grants, conducting pioneering studies in transplant and other treatments for hematologic malignancies. He has served as a principal investigator for clinical trials focused on myelodysplastic syndrome, stem cell transplantation, and other aspects of hematology. He has authored more than 100 papers published in prominent medical journals and has also served as a reviewer and editor for many journals.

Dr. Lim is licensed to practice medicine through the States of Texas and New York. He is certified in Internal Medicine & Hematology by the Royal College of Physicians (London) and in Hematopathology by the Royal College for Pathologists.

He is a member of the Fellowship of the Royal College of Physicians (London), the Fellowship of the Royal College of Pathologists (UK), the American Association of Immunologists, FASEB, and the International Society for Biological Therapy of Cancer. He is also a member of the editorial board of American Journal of Blood Research and is an editor of World Transplant Journal.

Dr. Lim brings novel approaches in stem cell transplant for the treatment of blood and marrow cancers to CTCA. He is passionate about his patients and the care he provides. “I treat my patients as my friends and family members,” he says.

Outside of CTCA, Dr. Lim enjoys spending time with his wife and three children. “My life spins around my patients and my family,” he says.
