Myth 1: Only Smokers Get Lung Cancer

Fact: While smoking is the leading cause of lung cancer, non-smokers are also at risk. In fact, about 10–20% of lung cancer cases occur in people who have never smoked. Other risk factors include:

• Exposure to radon gas

• Secondhand smoke

• Air pollution

• Occupational exposure to carcinogens (like asbestos or diesel exhaust)

• Genetic predisposition

Myth 2: If You’ve Smoked for Years, There’s No Point in Quitting

Fact: It’s never too late to quit smoking. Quitting at any age can significantly reduce your risk of lung cancer and improve your overall health. Even after decades of smoking, lung tissue begins to heal once smoking stops.

Myth 3: Lung Cancer Is Always Fatal

Fact: While lung cancer has a lower survival rate compared to some other cancers, it is treatable—especially when caught early. New therapies, including targeted treatments and immunotherapy, have greatly improved outcomes. The five-year survival rate has steadily increased thanks to early detection and better treatment options.

Myth 4: A Chronic Cough Is Just a Cold or Allergies

Fact: A persistent cough lasting more than 2–3 weeks should never be ignored. While it may be due to a cold or allergies, it could also be an early sign of lung cancer. Other warning symptoms include:

• Chest pain

• Shortness of breath

• Hoarseness

• Unexplained weight loss

• Coughing up blood

Myth 5: Lung Cancer Only Affects Older People

Fact: Lung cancer can affect people of all ages, though it is more common in individuals over 65. In recent years, more younger adults—especially non-smokers—have been diagnosed, possibly due to environmental exposures or genetic factors.

Myth 6: Screening Isn’t Necessary Without Symptoms

Fact: Lung cancer screening with a low-dose CT scan is recommended for people at high risk—such as long-term smokers—even if they feel fine. Early-stage lung cancer often has no symptoms. Screening can detect tumors before they grow or spread, significantly increasing survival chances.

Myth 7: Lung Cancer Patients Shouldn’t Exercise

Fact: Many patients can safely engage in physical activity during and after treatment. Moderate exercise can help reduce fatigue, improve lung function, and boost mental well-being. Always consult your doctor before starting any new routine.

How to Lower Your Lung Cancer Risk

• Quit smoking and avoid secondhand smoke.

• Test your home for radon—a leading cause of lung cancer in non-smokers.

• Wear protective gear if exposed to chemicals at work.

• Follow a healthy diet and exercise regularly.

• Talk to your doctor about lung cancer screening if you’re in a high-risk group.
