ACS Cancer Screening Guideline Development Group Members

This Cancer Screening Guideline Development Group (GDG) was appointed by the American Cancer Society (ACS) Board of Directors to create all ACS cancer screening guidelines. The ACS GDG consists of 10 clinicians and population health care professionals as well as 1 patient advocate.

The group’s task is to supervise the review of evidence and transform the evidence into written guidelines. While they consider content-specific input and the opinions of expert clinical specialists, their focus on evidence avoids professional conflicts of interest.

Ruth Etzioni, PhD
Professor of Public Health Sciences Division, Fred Hutchinson Cancer Center in Seattle, Washington

Biostatistician, Epidemiologist

In addition to serving on the ACS GDG, Dr. Ruth Etzioni serves on 3 national panels on prostate cancer early detection.
