About
Keith M. Bellizzi is a leading health psychologist whose research focuses on cancer survivorship, aging, and the psychosocial and behavioral aspects of living with and beyond a cancer diagnosis. His work has profoundly shaped our understanding of how individuals adapt to chronic illness across the life course, particularly among older adults. Bellizzi’s major contributions include pioneering research on post-traumatic growth in cancer survivors, demonstrating that many patients experience positive psychological changes following diagnosis and treatment. He has also been instrumental in examining health behaviors, decision-making, and quality of life in prostate cancer patients, with notable work comparing recovery and return-to-work outcomes after different surgical approaches. His studies have garnered hundreds of citations, reflecting their significant impact on clinical practice and survivorship care guidelines. Bellizzi’s research has been supported by major grants from the National Cancer Institute, and he has served in leadership roles within the American Psychosocial Oncology Society. His work continues to inform interventions that help survivors thrive, not just survive.
