5 Signs You Should Get Checked for Lung Cancer

Lung cancer is the third most common cancer in the United States and one of the leading causes of cancer-related death. According to the CDC, lung cancer takes more lives annually than breast, prostate, and colon cancers combined.

Early detection is key. Knowing the signs and understanding your risk factors can make all the difference in getting timely treatment—and potentially saving your life.

1. You’re Struggling to Breathe Normally

Shortness of breath (also called dyspnea) is one of the most common early signs of lung cancer. You might feel tightness in your chest or find it harder to catch your breath—even during routine activities.

Don’t assume it’s just aging or allergies. If your breathing has noticeably changed, it’s time to speak with a doctor.

2. You’re Experiencing Chest Pain

As lung cancer progresses, many patients report persistent chest discomfort or pain. This pain may worsen with deep breathing, coughing, or laughing. In some cases, pain spreads to the back or shoulders.

If chest pain is new, severe, or doesn’t go away, you should be evaluated.

3. You’re a Smoker—or You Quit Recently

Smoking remains the #1 risk factor for lung cancer. The CDC reports that about 80–90% of lung cancer deaths are related to smoking.

Even if you’ve recently quit, your risk remains elevated for several years. The earlier you get screened, the better your chances of early detection.

4. You’ve Been Exposed to Secondhand Smoke or Radon

You don’t have to smoke to be at risk. Secondhand smoke is a proven cause of lung cancer. So is radon gas, an invisible and odorless substance that can accumulate in homes, especially in basements.

If you've lived in a home that tested high for radon or have been around tobacco smoke regularly, screening is strongly recommended.

5. You Have a Family History or Work Exposure

You may also be at higher risk if:

• You have a family history of lung cancer
• You’ve worked around asbestos, arsenic, cadmium, or diesel exhaust
• You’ve undergone prior radiation therapy to the chest

These exposures increase your lifetime risk of developing lung cancer—even decades later.

When to See a Doctor

Early lung cancer may not cause symptoms at all. That’s why screening is critical—especially if you're 50 or older and have a history of smoking or occupational exposure.
