A new type of cancer detection test has been invented in Shanghai that can make cancer detection a quick, easy and comprehensive process for several organs of the body at the same time.
The test looks for biomarkers that typically indicate the presence of cancer in the pancreas, stomach and colon using just a single drop of dried blood.

Although the test is in its early stages, early trials reveal its benefit in preventing deadly types of cancer that are often discovered too late.

It is said that the credit goes primarily to the supercomputers that helped researchers in Shanghai create this new test, and it is expected that researchers will use artificial intelligence techniques to achieve more accurate results in the future.

According to research published in some websites specialized in the medical field, this method aims to search for metabolites, or what are scientifically called metabolites, which are by-products of the cell metabolism process, and these products – including: alanine, lysine, arginine, glucose, and sugar – are found in varying concentrations in the blood. Even in healthy individuals.

Given that cancer is characterized by uncontrolled growth and random spread of its cells, cell metabolism must clearly change when cancer appears, leading to a significant increase in the proportion of some of these byproducts. This applies to types of cancers. Such as: pancreatic cancer, stomach cancer, colon cancer, and rectal cancer.

The new test begins by taking a single drop of a patient’s blood and letting it dry on a cotton swab. Using nanoparticle-enhanced laser desorption and ion mass spectrometry, researchers estimate the concentration of each metabolite. The abundance of a particular metabolite, or in some cases the presence of multiple metabolites at the same time, indicates To the possibility of cancer.

The researchers found that the new testing method achieved an accuracy of up to 81.2% in people with pancreatic cancer, and the researchers estimate that it could reduce the cases of undiagnosed pancreatic, stomach, colorectal cancer by between 20.35% and 55.10%, due to early detection.

While getting tested quickly and easily can help patients’ lives and relieve the anxiety of waiting for a result, we’re unlikely to see it in everyday medical fields any time soon.
