November Marks Lung Cancer Awareness Month: What to Know About Risks and Screening

November is Lung Cancer Awareness Month, a time dedicated to raising awareness about one of the leading causes of cancer-related deaths and the importance of early detection.

According to the Centers for Disease Control and Prevention (CDC), lung cancer is the leading cause of cancer deaths in the United States among both men and women.

Cigarette smoking remains the leading risk factor for lung cancer, accounting for approximately 80% of lung cancer deaths nationwide. Other risk factors include exposure to secondhand smoke and radon.

Lung cancer often does not cause noticeable symptoms until the disease has advanced. When symptoms do occur, they may include a persistent or worsening cough, chest pain, shortness of breath, coughing up blood, unexplained weight loss and fatigue.

The U.S. Preventive Services Task Force recommends annual lung cancer screening using low-dose computed tomography (CT) scans for adults who meet all three of the following criteria:

  • Are between 50 and 80 years old.
  • Have a smoking history of at least 20 pack-years.
  • Currently smoke or have quit within the past 15 years.

A pack-year is calculated by multiplying the average number of packs of cigarettes smoked per day by the number of years smoked. For example, smoking one pack daily for 20 years or two packs daily for 10 years equals 20 pack-years.

Screening can help detect lung cancer before symptoms develop, when treatment may be more effective.

Health officials encourage individuals with a history of smoking or concerns about their lung health to speak with a healthcare provider about their risk factors and whether screening is appropriate.

Lung Cancer Awareness Month also emphasizes the importance of smoking cessation, reducing exposure to secondhand smoke and recognizing potential warning signs.
