A Quiet Threat: Why Lung Cancer Screening Matters

November is Lung Cancer Awareness Month — a timely reminder to address a silent threat. Lung cancer often develops with few or no symptoms, making early detection critical. Some people may notice a persistent cough, shortness of breath, or a “short fuse” or increased fatigue — but many times, warning signs are subtle or absent.

According to the Centers for Medicare & Medicaid Services (CMS), you may be eligible for annual screening with a low-dose computed tomography (LDCT) scan if you meet all of the following criteria:

• Age 50–77 years
• No known signs or symptoms of lung cancer
• A smoking history of at least 20 “pack-years” (for example, one pack per day for 20 years)
• Are a current smoker or quit within the past 15 years

While national lung cancer rates have generally declined due to reduced smoking, several states, including Nebraska, have seen small upticks in recent years. This underscores the importance of staying vigilant about screening and lung health.

Because symptoms can be minimal or mistaken for other conditions — and because the disease remains one of the leading causes of cancer-related death — it is vital to get checked if you have any symptoms or a history of smoking.

If you currently smoke or have smoked in the past, contact your primary care provider to discuss whether you qualify for lung cancer screening. Early detection saves lives.
