How they were screened
| Test (within the recommended interval) | Share of adults 50–75 |
|---|---|
| Any recommended test | 67.0% |
| Colonoscopy in the past 10 years | 60.6% |
| Stool test — gFOBT or FIT in the past year, or FIT DNA in the past 3 years | 11.3% |
| Sigmoidoscopy or CT colonography in the past 5 years | 3.1% |
The recommended options
For adults at average risk, the USPSTF recommends screening from 50 to 75 with any of these tests, at these intervals:
| Test | How often |
|---|---|
| Colonoscopy | every 10 years |
| Flexible sigmoidoscopy or CT colonography | every 5 years |
| Flexible sigmoidoscopy plus a yearly fecal immunochemical test (FIT) | sigmoidoscopy every 10 years |
| FIT DNA test | every 3 years |
| Guaiac-based fecal occult blood test (gFOBT) or FIT | every year |
About the numbers
The figures come from household interviews in the National Health Interview Survey. Adults 40 and older were asked whether, and when, they'd had each test; they could report more than one. People with a history of colorectal cancer were excluded.
