CT Lung Cancer Screening Program Frequently Asked Questions

The LDCT examination itself takes less than 10 seconds, and overall you should be done within 10 minutes. No medications are given, and no needles are used. You can eat and drink before and after the exam. You don't need to change your clothes as long as the clothes on your chest do not contain metal. You must be able to hold your breath for approximately 5 seconds while the CT examination is being performed.

There are some risks and limitations of LDCT lung cancer screening. These potential risks include:

• Radiation Exposure
  By using special techniques, the amount of radiation in LDCT lung cancer screening is small, averaging the amount of radiation a person would receive from living in the United States for 4 months.
• False Positive Test Result and Additional Testing
  LDCT lung cancer screening can show a “false positive” test result. The patient may need to have more tests, which will be performed only with permission of the patient and the referring care provider. If the patient needs a procedure, such as a biopsy, it can have potential side effects.
