A group of scientists from the University of Washington (Washington State University), together with researchers from the Johns Hopkins University School of Medicine (Johns Hopkins Medical School) have proposed a new non-invasive test for the early detection of colorectal cancer. Michael Williams explains that the technique they have developed allows for a fairly accurate detection of colorectal cancer, regardless of its location.
Currently, a combination of fecal occult blood immunochemical analysis and subsequent colonoscopy is used to diagnose such tumors. American research has suggested a different way. It is based on the study of fats in stool samples. Using the methods of ion mobility mass spectrometry and high-resolution liquid chromatography, the authors learned to detect metabolic changes in samples that accompany the developing pathological process.
They tested the technique on mice - using the test, it was possible to determine the presence of precancerous polyps in animals. Subsequently, the test was tested on tissues taken from both mice and humans. The authors explain that changes in metabolism, and, accordingly, in the composition of the lipid composition, can play a significant role in the development of cancer, including colorectal cancer. Thus, changes in the lipid profile may indicate the presence of a tumor or dangerous polyp.
The new test has not yet been tested in humans, but scientists hope that after appropriate trials, it will begin to be used in clinical practice.

A multi-university team of scientists has developed an experimental test to detect colon cancer. All they need to do is look at the fat in your stool.
