[New tool for detecting lung cancer] Lung cancer is still the main cancer killer, but once it is discovered it is too late. Recently, however, the researchers found that one day, with a simple nasal swab, they could quickly scan for lung cancer using CT.
The key is the DNA-based biomarkers in the nasal cavity, which can be seen whether the lung damage is cancerous. "The cancerous information contained in the nasal gene expression contributes to the detection of lung cancer. This test allows doctors to quickly confirm the disease and save the patient a large amount of subsequent examination fees," the researchers said.
Currently, doctors perform chest scans on long-term smokers or other high-risk groups. Once an abnormality is found, a series of tests, such as biopsy, are essential. Therefore, a more convenient, concise, safe and effective detection method is needed.
In the study, the researchers removed nasal swabs from previous or current smokers and identified 30 groups of genes related to lung cancer. Two lung cancer experts said the technology is very promising and helps reduce lung cancer. Some unnecessary programs in the diagnosis process.
