Final answer:
The USPSTF recommends screening for lung cancer in patients with a significant smoking history, such as this 58-year-old male with a 20-pack-year history who quit 1 yr ago.
Step-by-step explanation:
The patient in question, a 58-year-old male with a 20-pack-year smoking history who quit 1 year ago, should be screened for lung cancer according to United States Preventive Services Task Force (USPSTF) guidelines. A strong correlation has been established between cigarette smoking and an increased risk of lung cancer, with significant data showing that the risk of dying from lung cancer is greatly elevated in smokers compared to non-smokers. Despite cessation, the effects of smoking on lung cancer mortality can take up to 20 years to manifest. Therefore, lung cancer screening is recommended for those with a significant smoking history, typically with low-dose computed tomography (LDCT).
