The United States spends more than $40 billion annually on initial cancer screenings, with almost two-thirds of this amount attributed to screening for colorectal cancers, according to a peer-reviewed study. “Approximately 88.3 percent of costs were attributable to private insurance; 8.

5 percent to Medicare; and 3.2 percent to Medicaid, other government programs, and uninsured persons,” according to the study. Roughly 64 percent of the total cost of cancer screenings was for colorectal cancer.

Facility costs—the payments to centers conducting the tests—were found to be a major driver of cancer screening expenses. Researchers said that the $43 billion estimated cancer screening costs are lower than the reported cost of cancer treatment in the United States in the first year after diagnosis. They noted that screening may decrease cancer mortality and treatment costs.

“Identification of cancer screening costs and their drivers is critical to help inform policy and develop programmatic priorities, particularly for enhancing access to recommended cancer screening services,” the researchers wrote. No funding sources were reported. Cancer screening is crucial for people at risk of the disease, and detecting cancer earlier can reduce the cost of treatment.

In addition, people can often continue to work while getting early treatment. “This trend is largely affected by the aging and growth of the population and by a rise in diagnoses of 6 of the 10 most common cancers—b.
