If you’re referring to a newer, less-invasive approach to colorectal cancer screening, the claim needs a little context. Colonoscopy is still an important diagnostic and screening procedure; it hasn’t simply been replaced.
A more accurate headline would be:

New Methods Could Make Colorectal Cancer Screening Less Invasive
Colonoscopy may not be the only way to screen for colorectal cancer in the future.
Newer non-invasive or minimally invasive tests, including stool-based tests and blood-based approaches under development, are being studied to detect signs of colorectal cancer without inserting a camera into the colon.
However, there is an important distinction: screening tests and colonoscopy do different jobs. A positive stool or blood test may still require a colonoscopy to examine the colon directly and, when necessary, remove suspicious polyps.
So while technology is making colorectal cancer screening easier and less invasive, colonoscopy remains an important tool for diagnosis and treatment.
