Guardant Health via The Harris Poll recently asked more than 1,000 colorectal cancer screening-eligible American adults about their screening preferences. Key findings are reported in a press release.

The survey respondents were asked about multiple screening methods like traditional colonoscopies, blood tests, and stool tests. Key findings:

  • More than 90% of polled individuals would like to see blood-based colorectal cancer screening be covered by insurance.
  • Nearly three-quarters (71%) are anxious about undergoing a colonoscopy.
  • If the U.S. Food and Drug Administration (FDA) approved a blood test for colorectal cancer screening, 77% of respondents said they would likely follow through with screening without delay.
  • Most respondents reported willingness to receive a follow-up colonoscopy if a blood test revealed need.
  • Stool tests were not the preferred screening method for polled individuals, with 38% reported difficulty undergoing one and 54% reported being grossed out by them.
