Colorectal cancer is the third-most common malignancy in the United States and the second-leading cause of cancer-related mortality.

Although screening is universally recommended in the United States, screening rates are low nationally and among racial and ethnic minorities.

The May Laboratory works with collaborators in public health, informatics, general internal medicine, and biostatistics to design and implement interventions to increase uptake of colorectal cancer screening and to improve completion of diagnostic follow-up when screening is abnormal.
Research in this area also includes analyses utilizing publicly available national- and state-level databases to evaluate screening rates and cancer outcomes.

The portfolio of work encompass both health disparities research and health systems quality improvement research, but goes beyond.
