We have developed a patented technology that will test a sample of a patient's breath to screen for lung cancer. Early detection is key to survival. There are 15 mm persons in the US who are in the high risk group of persons aged 54 or older with a smoking history of 30 pack years. With over 700 patients studied, the test has a sensitivity of 94% and a specificity of 86%. Easy to use and low cost. Future tests: other cancers and diseases.
