Spotlight on Preventive Health: Screening Recommendations for Smokers
By: Noor Arshad, MD.,

Smoking remains a leading risk factor for numerous serious health conditions, including abdominal aortic aneurysm (AAA) and lung cancer. For individuals with a history of smoking, early screening is a critical tool for preventing complications and improving survival rates. The U.S. Preventive Services Task Force (USPSTF) offers the following evidence-based screening guidelines for high-risk individuals:
Abdominal Aortic Aneurysm (AAA) Screening
Who to Screen:
Men aged 65 to 75 years who have ever smoked.
What to Do:
Offer a one-time abdominal ultrasound to screen for AAA.
Why It Matters:
Smoking increases the risk of AAA, a condition that can lead to a life-threatening rupture if undetected. A simple, non-invasive ultrasound can detect aneurysms early, allowing for monitoring or surgical intervention when necessary.
Lung Cancer Screening
Who to Screen:
Adults aged 50 to 80 years with a 20 pack-year smoking history who currently smoke or have quit within the past 15 years.
What to Do:
Recommend annual low-dose computed tomography (LDCT) to screen for lung cancer.
When to Stop Screening:
Discontinue screening once the individual has not smoked for 15 years, develops a health problem that substantially limits life expectancy, or is unable or unwilling to undergo curative lung surgery.
Why It Matters:
Lung cancer often presents late and is associated with high mortality. Annual LDCT screening in high-risk individuals has been shown to reduce lung cancer deaths by enabling earlier diagnosis and treatment.
Takeaway for Healthcare Providers
Discuss smoking history routinely with patients aged 50 and older. Appropriate screening can lead to the early detection of serious diseases and offers a vital opportunity to engage patients in smoking cessation and preventive care.
