Slide 5Number of People requiring CRC Screening and Follow-up Procedures (in millions)

SLIDE 5 NOTES: We attempted to determine the size of the U.S. population that has not been screened and the number of tests needed under a series of scenarios to screen those people.

From the 76.5 million individuals in the U.S. age 50 or greater, we removed 6.5 million persons who would be deemed “high risk” from these categories. High-risk is based on family history of colorectal cancer or history of pre-disposing conditions. Those data come from SEER (NCI), National Health Interview Survey (CDC), and National Institute of Diabetes and Digestive and Kidney Diseases (NIH) databases.

The average-risk population is 70 million. We used NHIS data to determine which of those individuals would already have been screened, which eliminates 28.2 individuals. Thus, almost 42 million people ages 50 and older have not been screened according to current screening guidelines.
