More than 60 years after the landmark 1964 Surgeon General's report linked cigarette smoking to lung cancer, smoking remains the leading cause of the disease. Oklahoma has historically had a higher smoking rate than the national average, and lung cancer remains a major cause of death in the state. Understanding the risks — and the value of early detection — can save lives.

Key Points

• Lung cancer is the leading cause of cancer death in the U.S.
• Survival is far higher when lung cancer is found before it spreads.
• Most lung cancers are diagnosed at a later stage.
• Annual low-dose CT screening is recommended for many current and former smokers ages 50 to 80.

Smoking in Oklahoma

Statewide programs to help people quit have contributed to declining smoking rates, but Oklahoma has long ranked among the states with higher percentages of adult smokers. Smoking affects every demographic group, and its effects extend beyond lung cancer to heart disease, COPD and other illnesses.

Why Stage at Diagnosis Matters

National cancer statistics show a stark difference in outcomes by stage. When lung cancer is found while still localized, roughly 6 in 10 people survive at least five years. Once it has spread to distant organs, five-year survival drops to fewer than 1 in 10. Unfortunately, the majority of lung cancers are diagnosed after they've already spread, largely because early-stage disease usually causes no symptoms.

Steps to Lower Your Risk

1. Quit smoking

It's the single most important step. Free help is available through the Oklahoma Tobacco Helpline at 1-800-QUIT-NOW.

2. Avoid secondhand smoke

Nonsmokers exposed to secondhand smoke at home or work have a 20% to 30% higher risk of lung cancer, according to the CDC.

3. Test your home for radon

Radon, a naturally occurring radioactive gas, is the second leading cause of lung cancer in the U.S. Inexpensive test kits can check your home. Also be aware of exposure to asbestos and other carcinogens.

4. Ask about screening

Low-dose CT is the recommended tool for lung cancer screening. The U.S. Preventive Services Task Force recommends annual screening for adults 50 to 80 with a 20 pack-year smoking history who currently smoke or quit within the past 15 years. CT can also reveal emphysema and other lung conditions. Learn more on the lung scan page.

The Takeaway

Lung cancer is far more treatable when caught early. If you smoke or used to, talk with your doctor about screening. Advanced Body Scan provides lung imaging at its Oklahoma City location, and its FAQ explains what to expect.
