Know your risk.

A lung cancer screening is done to detect the presence of lung cancer in individuals who do not yet show symptoms of the disease. It is particularly recommended for long-term smokers and those at high risk due to their smoking history and age.

Lung cancer screenings are usually performed using a low-dose computed tomography (LDCT) scan. This type of scan uses X-rays to create detailed images of the lungs, which can help detect abnormalities or signs of cancer.

Before: You will receive specific instructions from your healthcare provider, usually to avoid eating or drinking for a few hours before the scan.

During: During the scan, you will lie on a table that slides into the CT scanner. You will need to stay still and may be asked to hold your breath briefly to get clear images.

After: There is no downtime after the scan, and you can typically go about your day normally. Your doctor will review the images and discuss the results with you during a follow-up appointment.

You should wear comfortable clothing and remove any jewelry or other metal objects that might interfere with the imaging. Follow any other specific instructions given by your healthcare provider.

Bring a photo ID, your insurance information, and any forms or documents provided by your doctor’s office. Also, bring a list of any current medications you are taking.

Benefits: The primary benefit is the early detection of lung cancer, which can significantly improve the chances of successful treatment and survival.

Risks: There are minimal risks associated with low-dose CT scans. There is exposure to low levels of radiation, but the potential health benefits outweigh the small risk. There’s also a possibility of false positives that could lead to further testing or unnecessary anxiety.
