Researchers used an unexpected source of early detection of bunny pancreatic cancer, and this source is stool samples.
The intestine is a home to trillions of bacteria, and in fact the number of bacterial cells in the body exceeds the number of human cells by about 40 to 30 trillion cells, and these microscopic organisms make up complex societies that can reflect human health or illness.
The study was conducted by researchers from the University of Helsinki Finnish and Shahid University of Hashti for medical science in Iran, and its results were published in the Gut Pathogens magazine, and the British newspaper Independent was written about it.
The pancreatic cancer was dubbed with a “silent killer” for a good reason. With the appearance of symptoms on most patients, the disease often has reached an advanced stage in which treatment options become very limited.
Benin bench cancer develops in the pancreatic canal, a tube that connects the pancreas to the small intestine, when the tumors are formed here, they may impede the flow of digestive enzymes causing problems in energy metabolism, which makes patients feel chronic fatigue and weakness, and these symptoms are often hidden, to the point that it is easy to ignore or attribute to other causes.
Since the pancreatic cancer is usually evolved in the part of the intestine of the pancreas, and because most people have regular bowel movement, stool samples provide a practical and non -surgical window on what is happening inside the body.
The researchers collected stool samples and analyzed the DNA of bacteria, and the results of the Finnish Iranian study were amazing.
Pancreatic cancer patients showed a decrease in bacterial diversity in their intestine, with the increase or decrease in some types compared to healthy people.
More importantly, the team has developed an artificial intelligence model that can distinguish accurately between cancer and health patients, based on their intestinal bacterial files only.
The bilateral reactions between cancer and bacteria are particularly interesting, so some bacterial features can not only indicate the presence of the disease, but the disease itself can change the microbium of the intestine.
