Lung Cancer Screening

More people die of lung cancer each year in the United States than any other type of cancer, yet when it’s caught early, there are more treatment options and higher survival rates. In fact, annual screening with CT scans can detect lung cancers in their earliest stage, and up to 90 percent can be cured.

Based on screening guidelines established by the National Comprehensive Cancer Network, patients who are considered high-risk for lung cancer may find benefit in having a low-dose CT screening to detect early lung cancer.

What is CT screening?

Computed tomography (CT or CAT scan) is a diagnostic test that uses a combination of X-rays and computer technology to create cross-sectional images (often called slices), horizontally and vertically, of the body. A CT scan shows detailed images of the bones, muscles, fat, blood vessels and organs.

As a result, CT scans are very detailed and help physicians diagnose many conditions that may not be as easily diagnosed with other imaging methods like X-ray or ultrasound.

Who is eligible for a CT lung cancer screening?

Patients who meet the guidelines developed by the National Lung Screening Trial and the National Comprehensive Cancer Network are eligible for a CT lung cancer screening, with a written order from a physician. This screening program involves having an annual chest CT scan for three years.

Eligible participants must meet the following criteria:

  • individuals between 55 and 74
  • current or former smoker with a history of at least 30 “pack years” of smoking (one “pack year” is equal to the number of packs smoked a day times the number of years of smoking)
