Gallery test detects cancer at an early stage

An important medical study was conducted in North America. This was reported by Zamin.uz.

Scientists tested a blood test capable of detecting more than 50 types of cancer at an early stage. This research was carried out with over 25,000 participants in the United States and Canada.

According to the results, the test detected cancer risk in one out of every hundred people. Subsequent examinations confirmed the disease in approximately 62 percent of them.

Interestingly, half of the detected cases corresponded to the early stage of cancer. This indicates that this new method is of great importance for early diagnosis.

The test showed 99 percent accuracy in indicating the absence of cancer in healthy individuals and correctly identified the source of cancer in nine out of ten cases. The test is called Galleri and was developed by the American company Grail.

It detects fragments of DNA released into the blood by cancer cells. Currently, this test is also being trialed by the United Kingdom's National Health Service (NHS).

Experts emphasize that when the Galleri test is used together with conventional screening methods for breast, lung, colon, and cervical cancers, the accuracy increases sevenfold. This allows doctors to detect the disease at a much earlier stage.

However, scientists from Cancer Research UK remind that the test may sometimes indicate changes that do not harm the body as cancer. Therefore, cautious use and additional research are necessary for now.

Next year, the results of a three-year trial involving 140,000 patients in England will be announced. If the results are positive, the Galleri test is planned to be applied to another 1 million people.

According to Sir Harpal Kumar, a representative of Grail company, the main goal is to expand the possibility of detecting and treating the disease not late, but at an early stage. He emphasized, "Most patients die because cancer is diagnosed late.

We aim to change this." Thus, a new era may begin in the field of medicine.

The ability to detect cancer early through blood tests raises great hope for saving human lives.
