About PECaD

Our mission

The mission of PECaD is to ensure that all cancer patients and communities benefit from the clinical and scientific advances at Siteman. We strive to reduce the cancer burden and related disparities, while engaging communities to promote health equity across Siteman’s catchment and beyond.

We fulfill this mission by:

  • Accelerating outreach, education and access to clinical resources in Siteman’s catchment;
  • Monitoring the cancer burden and related disparities in Siteman’s catchment population to inform where to direct research and resources;
  • Fostering cancer disparities and community-engaged research;
  • Supporting efforts to promote diverse participation in clinical trials; and
  • Evaluating community engagement and progress toward achieving our goals
