According to TV2, recent media and scientific reports have revealed research progress that may open the door to a new method for early detection of lung cancer through exhaled air analysis, a technique that may allow the disease to be detected before it appears in traditional examinations such as X-rays or CT scans.
A serious illness and a delay in diagnosis
Health experts point out that lung cancer is one of the most dangerous and deadly types of cancer, and is often discovered at late stages due to the difficulty of detecting small tumors in traditional examinations. The Danish Cancer Society explains that the disease is mainly linked to smoking and that early detection contributes to improving survival rates and reducing complications.
A single exhalation may reveal the disease at an early stage.
Researchers at Lund University in Sweden are developing a technology that collects tiny particles from exhaled air and analyzes the proteins and genetic material they contain to detect cancer markers. Professor Sandra Lindstedt explains that the goal is to create a non-invasive and rapid test that can be used for early detection of the disease.
Great hope, but patience is necessary.
Professor and pulmonologist Ole Hilberg affirms that the idea could be “revolutionary” because it might allow for mass testing without the need for CT scans, but he emphasizes the necessity of thorough scientific verification of the results before clinical approval. Several countries are working on developing similar breath analysis technologies, but Lund’s team is nearing practical results.
Study methodology: comparison before and after tumor removal
Researchers collected exhaled breath samples from patients who underwent lung tumor removal surgery, both before and after the procedure, and then compared them to samples from healthy individuals to identify biomarkers associated with the disease. This comparison helps distinguish markers that disappear after tumor removal, enhancing the potential use of the test for early diagnosis and follow-up treatment.
Early detection tool in hospitals and health centers
Sandra Lindstedt believes that the technology could become a routine screening tool used in hospitals and primary healthcare centers in the future, making it easier to access early diagnosis outside the scope of advanced devices.
Millions of kronor for technology development
According to the source, the research project received significant funding from the Swedish Cancer Foundation to support the development of the technology and accelerate its clinical testing, which reflects the confidence of the funding bodies in its medical capabilities.
The study has not yet been published.
Experts point out that the study is still not scientifically published, which means that the final level of accuracy and reliability still needs independent scientific evaluation and academic review before it can be officially adopted.
Analysis of fine particles in exhaled air
The method relies on capturing microscopic particles containing proteins and RNA from lung tissue, then analyzing them to discover patterns associated with cancer. Other scientific research indicates that volatile organic compounds in exhaled breath can act as biomarkers for tumors, which enhances the feasibility of this type of test.
Distinguishing between types of lung cancer
Initial results showed that breath analysis may not only identify the presence of cancer, but can also differentiate between the main types of the disease, which may help doctors choose the appropriate treatment more quickly, according to the source.
Quick and gentle screening of at-risk groups
If the technology is adopted, it could become a quick and painless screening method for smokers or former patients, allowing for the expansion of early detection programs beyond major hospitals. European data suggests that early screening programs can significantly improve survival rates.
Scientific optimism is conditional on the final results.
Experts emphasize that there is still a long way to go before the test is routinely implemented, but the development represents a significant step towards the early detection of lung cancer. Ole Hilberg points out that the technology's success could accelerate its adoption in Denmark and make it available to general practitioners across the country, potentially saving many lives.
