Low-dose CT Lung Cancer Screening

What Is Low-Dose CT Lung Cancer Screening?

Low-dose CT lung cancer screening (LDCT) is a quick, non-invasive imaging test that checks your lungs for early signs of cancer—before symptoms appear. It’s designed for individuals at high risk for lung cancer due to smoking history or other factors, even if they feel fine.

This specialized CT scan detects small lung nodules (which may be early cancers) that a regular chest X-ray might miss. Catching these nodules early can significantly improve the chances of successful treatment and survival.

What to Expect During and After Your Screening

  • If Your Scan Is Normal:
    No further action is needed right away. Most patients return in one year for a follow-up screening.

  • If a Nodule Is Found:
    Don’t panic—a positive LDCT result doesn’t mean you have cancer. In fact, more than 95% of nodules are non-cancerous and may be caused by past infections or inflammation.

    Your doctor may recommend:

    • A follow-up LDCT in a few months to monitor the nodule

    • Additional imaging, such as a PET scan

    • A biopsy, if the nodule appears suspicious or changes over time
