Cancer is one of the leading causes of death in the world, and the number of patients is increasing every year. It is possible, however, that a revolution awaits us, and the key to it is a quick and simple blood test, known as the Galleri test. Scientists say the “medical holy grail” can detect more than 50 types of cancer before symptoms appear, and can even pinpoint where severe changes are forming. The largest research on the effectiveness of the Galleri test in the world has just started in Great Britain. What is what types of cancer can it detect?
- Cancer is one of the leading causes of death worldwide. Every day, 26 thousand people die because of it. people (data for 2018)
- In the treatment of cancer, the time to detect the disease is of great importance – the earlier the lesions are diagnosed, the greater the chances of survival are (up to ten times)
- A breakthrough in the early detection of cancer may come with the Galleri blood test. According to the researchers, the test can detect more than 50 types of cancer before the first symptoms appear. What is it about?

A Galleri blood test can detect cancer before it shows symptoms. How it’s possible?
The Galleri test gives hope for a change in the «rules of the game in early cancer detection». It’s a quick and simple blood test. Scientists hope it will detect 50 types of cancer before any symptoms of the disease appear. This is especially true for types of cancer that are usually difficult to identify earlysuch as cancer of the lung, pancreas, stomach, breast, cervix and intestine.

How is this possible? It is known that in some types of cancer, altered DNA fragments enter the bloodstream long before symptoms appear. The Galleri test, which is a genetic test, is designed to look for them. Their detection is not the definitive evidence of cancer, but it allows you to suspect the disease. Therefore, in a further step, additional research is necessary to confirm this or not. But this is not the end. The Galleri blood test determines what type of tumor it is and where it is located (in the case of tumors).
“This quick and simple blood test could mark the beginning of a revolution in cancer detection and treatment around the world,” said Amanda Pritchard, chief executive of NHS England.
Will it really be a breakthrough? It will show a pilot study of the Galleri test that began in the UK. It is the largest initiative of this type in the world – it is to cover 140 thousand. volunteers aged 50 to 77 years. They are conducted by Cancer Research UK and King’s College London together with the manufacturer of the test (currently available in the US).
Blood test for cancer detection. The world’s largest research has started
From September 13, participants in the study will be asked to report to the “mobile clinic” for a blood donation. This stage of the study will last one year. After one year, and then two, they will be asked to do the test again. A nurse will contact you if the test shows changes to the tumor. This patient will be referred to hospital for further testing.

The first results are expected by 2023. If the study is successful, the NHS plans to extend the test to another million people in 2024 and 2025.
“ We need to study the Galleri test carefully to find out if it can reduce the number of advanced cancers diagnosed, ” says one of the main researchers involved in the action, Prof. Peter Sasieni, director of Cancer Research UK and King’s College London Cancer Prevention Trials Unit. – The test can change the rules of the game in the early detection of cancer. We are happy that we can contribute to this, the scientist said.

Previous clinical trials show that blood tests allow to detect 51,5 percent. tumors at different stages of their development. Only 0,5 percent. cases, the results of the study were false positive (they indicated a neoplastic disease, which was not confirmed by further studies). In June, this was reported by the “Annals of Oncology”.
Tumors in numbers. 26 die every day people. Which kill the most?
Cancer is one of the leading causes of death worldwide. Every day, 26 thousand people die from it. people (data for 2018), and one in six deaths is a result of cancer. In 2020 alone, cancer took the lives of around 20 million people. Moreover, it can affect everyone, “young and seniors, rich and poor, men, women and children – it is a huge burden for patients, families and societies” stresses the World Health Organization (WHO). According to estimates, 2020 million people fell ill with cancer in 19,3, and in 2040 there are expected to be almost 30 million.
What cancers most often attack people and kill the most? The WHO has published a list on its website.
In 2020, the highest number of cases was recorded:
- breast cancer (2,26 million cases)
- lung cancer (2,21 million cases)
- colon and rectal cancer (1,93 million cases)
- prostate cancer (1,41 million cases)
- skin cancer – no melanoma (1,20 million cases)
- stomach cancer (1,09 million cases)
The cancers that took the greatest death toll in 2020 were:
- lung cancer (1,80 million deaths)
- colon and rectal cancer (935 deaths)
- liver cancer (830 deaths)
- stomach cancer (769 deaths)
- breast cancer (685 deaths)
Doctors and scientists have no doubts – the time of detection of the disease can be the difference between life and death. In other words, the earlier the lesions are diagnosed, the greater the chances of recovery. According to the National Health Service (NHS for short, the UK equivalent of our NHF), a patient diagnosed with cancer at the earliest stage is typically five to 10 times more likely to survive than patients who discover the disease after it has spread. to other parts of the body.

Unfortunately, some tumors develop for a long time without showing any characteristic symptoms. An example are, among others pancreatic cancer and stomach cancer.
