About Me

Dr. Hamdan is a cancer and blood disease doctor in Frankfort who cares for adults with many types of cancer. His care focuses on patient education, family involvement and treatment planning for cancers such as breast, lung, prostate and gastrointestinal cancer.

I grew up wanting to help people and later moved into oncology because every person’s cancer is different. I see my role as both doctor and teacher: “A doctor is more of a teacher.” I want patients and families to understand what to expect, what each treatment is meant to do and how we will work together. I also value involving loved ones when patients want that support, because cancer treatment is rarely something a person faces alone. I earned my medical education at Midwestern University Chicago College of Osteopathic Medicine, completed residency through the University of Illinois in Chicago / Advocate Christ Hospital & Medical Center, and completed fellowship at Midwestern University/Franciscan St. James Health. My clinical focus includes oncology and hematology, including care for breast cancer, lung cancer, prostate cancer and gastrointestinal cancers, as well as blood disease care.
