A new study on lung cancer detection presented at the American Thoracic Society International Conference in Denver concluded that long-time smokers and past smokers now have a more accurate way to detect whether or not they have lung cancer using CT scan technology. The study compared CT scans and standard chest x-rays to detect lung cancer. CT scans obtain a multiple-image scan of the entire chest, whereas a standard chest x-ray produces a single image of the whole chest. Results showed that patients receiving CT scans had a 15 to 20 percent lower risk of dying compared to those receiving standard chest x-rays.

The comparative study took place between September, 2014 and March, 2015 and gave CT scans to 375 patients of which 272 were eligible to continue in the program. Of this 272 patients, 19 had results that indicated malignant cancer.  Of those 19, 11 were confirmed malignant.  Eight of the 11 had lung cancer, and 3 had early stage lung cancer. Patients enrolled in the lung cancer detection program were considered high risk for lung cancer and all had a smoking history of at least 30 pack years that is the equivalent of smoking one pack of cigarettes a day for 30 years, and were current or former smokers without any signs or symptoms of lung cancer. The researchers said finding 3 early stage lung cancer patients  in the first 357 patients screened is incredible. Implementation of this program should save lives.
