AI-Powered Stool Test Shows Promise for Colorectal Cancer Detection
Scientists have created a new test that uses artificial intelligence to detect colorectal cancer from a stool sample.
This test analyzes bacteria in the gut and can identify cancer with 90% accuracy, which is similar to the accuracy of colonoscopies.
Unlike colonoscopies, this test is not invasive and can be done at home.
It is also more affordable.
Although promising, this new technology is still being researched and isn't ready for regular use.
Colonoscopies can still find and remove potential problems.
Researchers have developed a new method to detect colorectal cancer using an AI-powered stool test.
The test analyzes gut bacteria at the sub-species level to identify potential cancer.
The AI-powered test achieved a 90% detection rate in initial studies.
Stool-based tests offer advantages like being non-invasive, convenient, and affordable.
Colonoscopy remains the current gold standard and allows for the removal of precancerous polyps.
