Screening & Early Detection
Although screening may help doctors find and treat certain cancers early, there is currently no generally accepted screening test for lung cancer. Several methods of detecting lung cancer have been studied as possible screening tests including sputum (mucus brought up from the lungs by coughing), chest x-rays or spiral CT scans.
Worth Noting: Screening tests for lung cancer may accompanied by certain risks. Although research holds some promise for the future, studies so far have not shown that screening tests lower the number of deaths from lung cancer.
