The American Cancer Society updated its colorectal cancer screening guidelines on Wednesday to include a blood test as a new option [1].
This change aims to increase participation among individuals who avoid traditional screenings. By offering a simpler, non-invasive alternative, health officials hope to identify cancers at an earlier stage [2, 3].
The organization added two new screening options for colorectal cancer, one of which is the blood test [1]. While the test provides a more accessible entry point for patients, guidelines specify that it is not intended to replace the colonoscopy [2, 3, 4].
Medical professionals have noted that many patients skip recommended screenings due to the invasive nature of colonoscopies. The blood test serves as a tool to bridge that gap, providing a way to flag potential issues before more intensive procedures are required [3, 4].
Colorectal cancer screening typically involves a variety of methods depending on a patient's risk level and preference. The addition of this blood test expands the toolkit available to U.S. clinicians and patients to combat the disease [2, 3].
“The blood test serves as a tool to bridge that gap”
The inclusion of a blood test in official guidelines represents a shift toward patient-centric screening. By lowering the barrier to entry for colorectal cancer detection, the medical community is prioritizing higher screening volume over the immediate gold-standard accuracy of a colonoscopy, recognizing that any screening is more effective than none.
