In lung cancer screening studies as many as 30% of those screened have a lung nodule, the majority of which turn out to be benign. [15]
LEMS is often associated with lung cancer (50–70%), specifically small-cell carcinoma, [4] making LEMS a paraneoplastic syndrome. [5] Of the people with small-cell lung cancer, 1–3% have LEMS. [3] In most of these cases, LEMS is the first symptom of the lung cancer, and it is otherwise asymptomatic. [3]
[14] [15] [16] In the Mayo Clinic study, termed "The Mayo Lung Project," researchers randomized over 9,000 male smokers age 45 and older to receive either chest x-ray and sputum screening three times a year, or annual chest x-ray screening.

In the fifty years leading up to the Wynder and Graham study, lung cancer was observed to have risen dramatically and disproportionately in comparison to other cancers. From the 1920s to 1950, the year of the study's publication, deaths from lung cancer had quadrupled so now it was the leading cancer found in men. [8]
