Lung Cancer: What You Need to Know

Illustration of lungs.
  • Lung cancer is leading cause of cancer-related death in men and women.
  • Deaths from lung cancer exceed the number of deaths from breast cancer, prostate cancer and colon cancer combined.
  • Smoking is the primary cause of lung cancer, and quitting smoking is essential to prevention and treatment.
  • It’s never too late to quit! Even if you’ve been diagnosed with lung cancer, you will do better as an ex-smoker than a current smoker.
  • Common symptoms of lung cancer include coughing, wheezing, chest pain, shortness of breath and bloody mucus in the cough.

What can I do to lower my risk of lung cancer?

Smokers and former smokers make up more than half of new lung cancer cases, so the best thing to do is stop smoking. Other risk factors include secondhand smoke, radon, asbestos, air pollution and family history.

Should I be screened for lung cancer?

If you are between the ages of 55 and 80 and have smoked a pack of cigarettes per day for 30 years or two packs a day for 15 years, you may benefit from annual lung cancer screenings using low-dose CT scans.

What are the benefits of lung cancer screening?

Lung cancer is the most deadly cancer in the United States and will kill over 200,000 Americans this year. The high mortality of lung cancer is related to the fact that it is often diagnosed at a late stage, when it is incurable.

The benefits of lives saved by screening far exceed concerns over radiation exposure and costs of medical procedures needed to diagnose an abnormality seen on a CT scan.

Can e-cigarettes cause lung cancer?

Long-term health effects of e-cigarettes are not well-understood. Generally speaking, e-cigarettes are less toxic than normal cigarettes, but many still contain known cancer-causing compounds. More recent research has suggested that e-cigarettes put users at greater risk for respiratory infections.
