Our Medical Experts

Fight CRC’s Medical Advisory Board and expert workgroups play a vital role in moving our mission of supporting patients and finding a cure forward.

Our Medical Advisory Board (MAB) ensures that the information Fight Colorectal Cancer presents is accurate and credible. Researchers, doctors, and nurses volunteer their time on a renewable two-year commitment. The goal of the MAB is to ensure colorectal cancer patients are well-informed about their options when it comes to fighting colorectal cancer.

Please email our Patient Resources team if you’re a medical professional interested in joining our Medical Advisory Board.
