Color Sensor Breath Test Can Detect Lung Cancer

This sounds pretty cool. There is a new revolutionary breath test that can be used to detect lung cancer with "moderate accuracy" even in the early stages. This test uses a chemical color sensor that can detect tiny changes in the unique chemical signature of the breath of people with lung cancer. When a patient has lung cancer, the lung cancer cells undergo metabolic changes, leading to the production of volatile organic compounds, which are detected in the breath of these patients. A study on the test reveals that it can be used to accurately predict the presence of cancer in approxiamately three out of four people with lung cancer. Another important characteristic of the test is that it is not affected by age, gender, or stage of disease. In the past, other methods have been used, such as gas chromatography and mass spectrometry, but these require more skill and are quite costly.
