Lung cancer remains the leading cause of cancer-related death in the United States, but early detection saves lives. Thanks to low-dose CT (LDCT) screening, doctors can now find lung cancer at earlier, more treatable stages. However, not everyone needs this screening—guidelines help identify who will benefit most.

According to the U.S. Preventive Services Task Force (USPSTF), adults should consider annual lung cancer screening if they meet these criteria:

✅ Aged 50 to 80 years
✅ Have a 20-pack-year smoking history (for example, smoking one pack a day for 20 years)
✅ Currently smoke or have quit within the past 15 years

Low-dose CT scans are painless and take only a few minutes. Unlike standard chest X-rays, LDCT is much better at detecting small lung nodules before they cause symptoms. In large studies, this screening has been shown to reduce lung cancer deaths by up to 20%.

If you qualify, yearly screening can become part of your preventive care plan. It’s important to talk with your doctor about the risks and benefits. While LDCT can detect cancer early, it may also find nodules that are not cancerous, leading to additional tests or procedures.

For people who do not meet the screening criteria, routine screening is generally not recommended. However, any persistent cough, unexplained weight loss, or shortness of breath should always be evaluated right away.

At Pulmonary & Medicine Associates, we help you understand your lung cancer risk and whether screening is right for you. If you’re eligible, we’ll guide you through each step—from scheduling your scan to follow-up care—so you feel informed and supported.

Don’t wait for symptoms to appear. Early detection could save your life.
