Lung Cancer

Low-dose CT (LDCT) scans can find lung cancer before symptoms appear. Screening is only recommended for people at high risk due to age and smoking history.

  • Annual LDCT for adults 50-80 with a 20 pack-year history who currently smoke or quit within 15 years
  • Screening stops once you’ve been smoke-free for 15 years or have major health issues
  • Pair with smoking cessation, vaccinations, and routine primary care visits
*Average vs. high risk for lung screening
  • Average risk: most people without heavy smoking history — LDCT screening not recommended
  • High risk: ages 50-80, 20+ pack-years, currently smoke or quit within 15 years; consider stopping after 15 years smoke-free

Low-Dose CT

A fast, painless scan that uses low radiation to capture detailed lung images. It’s the gold standard for lung cancer screening and takes less than a minute.

Smoking History Review

Your provider will calculate “pack years” (packs per day × years smoked) to confirm eligibility. Share nicotine replacement or vaping history too.

Shared Decision Visit

Medicare and most insurers require a counseling visit to weigh benefits, radiation exposure, and follow-up plans before your first LDCT.

After the Scan

Most LDCT results are normal. If spots (nodules) are found, a lung specialist will schedule repeat scans or a biopsy depending on size and growth.
