U.S. scientists have created breath test that can detect lung cancer in patients even in the early stages of the disease.
By means of a simple colour test which shows up unique chemical changes in the breath of people with lung cancer, the disease was accurately detected in just under three out of four people with the disease.
By using a sensor just slightly bigger than a coin, which is relatively cheap and easy to use, unique chemical changes in the breath of people with lung cancer could be seen with a series of coloured dots.
After breathing into the device for 12 minutes the hues of a series of 36 dots provide a gas fingerprint for lung cancer.
Because the test can detect the disease at its earlier stages, patients can start receiving treatment when it's most effective.
