Newly engineered yogurt bacteria able to detect colorectal cancer via a urine test could make colonoscopies obsolete.
The yogurt-test method was developed by Sangeeta Bhatia, a professor at MIT who has been working to create synthetic molecules that can enter the body in spoonful of yogurt. Once in the body, these molecules interact with the cancer to create distinctive biomarkers that collect in the urine and can be detected by a paper-based urine test. In studies so far, the test has been effective in identifying both colorectal cancer and liver fibrosis in mice.
The new technology could particularly benefit developing nations, where few people are regularly screened for cancer, as well as replace conventional colonoscopies.
