Lung Cancer Facts 2023

Facts About Lung Cancer

LUNG CANCER is the leading cause of cancer death worldwide.1

AN ESTIMATED 238,340 PEOPLE will be diagnosed with lung cancer in 2023 in the U.S.2

1 IN 16 PEOPLE will be diagnosed with lung cancer in their lifetime – 1 in 16 men, and 1 in 17 women.2

LUNG CANCER kills almost 3 TIMES as many men as prostate cancer. (source)

LUNG CANCER kills almost 3 times as many women as breast cancer. (source)

Approximately 127,070 AMERICAN LIVES are lost annually.2

654,620 PEOPLE IN THE U.S. TODAY have been diagnosed with lung cancer at some point in their lives.2

THERE IS HOPE. The number of new lung cancer diagnoses are declining steadily. Since 2006, the incidence rate decreased by 2.6% per year in men and 1.1% per year in women. Mortality rates are declining even faster, which likely reflects advances in treatment and early detection.2

Risk factors for Lung Cancer

Smoking is the leading risk factor for lung cancer and is responsible for 80% of lung cancer deaths. People who have never smoked account for 20% of lung cancer deaths.

Exposure to radon gas is the second leading risk factor of lung cancer.2

Other risk factors include exposure to:2

  • secondhand smoke
  • asbestos
  • certain metals (arsenic, chromium, cadmium)
  • certain organic materials
  • radiation
  • air pollution
  • diesel exhaust

Family history and genetic factors may also play a role in the development of lung cancer.2

People who have never smoked account for 20% of lung cancer diagnoses every year. An estimated 47,660 non-smokers will be diagnosed with lung cancer in 2023.3

Symptoms of Lung Cancer

See your doctor if you experience any of the following common symptoms of lung cancer:

B – Blood when you cough or spit
R – Recurring respiratory infections
E – Enduring cough that is new or different
A – Ache or pain in shoulder, back or chest
T – Trouble breathing
H – Hoarseness or wheezing
E – Exhaustion, weakness or loss of appetite

Other symptoms may include:

  • swelling in the neck and face
  • difficulty swallowing
  • weight loss

What you can do

Lung Cancer Screening

Early detection of high-risk lung cancer cases can reduce chance of death by up to 20%. If you smoke now or have in the past, ask your doctor if lung cancer screening may be right for you. Approximately 8 million Americans are at high risk for lung cancer and could benefit from a lung cancer screening …and yet only 5.7% actually get screened.4

Reduce your risk of lung cancer

If you smoke, get the help you need to quit. You can get help from state quitlines and other programs. Visit becomeanex.org or smokefree.gov, or call (800) 784-8669 [(800) QUIT-NOW].

Reduce exposure to radon. If you live in an area with high levels of radon, consider having your house tested for radon exposure and, if needed, take steps to reduce radon levels. More information is available at epa.gov/radon.

Help close the funding gap

Lung cancer claims about as many lives each year than breast, pancreatic, and prostate cancer combined.

But, these three cancers receive an average of 3x MORE RESEARCH FUNDING per life lost than lung cancer.2
