Analysis for worm eggs and at the same time – for cancer

DNA analysis of the stool allows you to identify different forms of cancer of the digestive systemElvira Koshkina, "Compulenta"
Previously, DNA testing of excrement was used only to detect bowel cancer in the initial stages.

Now, scientists from the Mayo Clinic in Minnesota (USA) have found that noninvasive testing is excellent for detecting malignant tumors in the gastrointestinal tract, that is, cancer of the pancreas, stomach, bile ducts and esophagus. 

The technique developed by scientists involves checking the patient's stool for DNA of cells that regularly peel off the surface of several types of tumors. Thus, it is possible to detect 65% of cases of esophageal cancer, 62% of pancreatic cancer, 75% of bile ducts and gallbladder, and 100% of stomach and intestines. This type of testing gives excellent results both in the early stages of the disease and in the late stages. 

Every fourth death from cancer is the result of malignant tumors of the gastrointestinal tract. These types of cancer are quite easy to treat if the disease is diagnosed at an early stage, which rarely happens. Most often, doctors conduct a colonoscopy examination of the large intestine, but this and other invasive techniques allow only one organ to be examined at a time. On the contrary, the new technology makes it possible to check several organs of the digestive tract for cancer at once.
