Dr. Zachariah Slattery, DO, answers our questions about the lung cancer screening process and what those going through the test need to know.
What factors would prompt a discussion about lung cancer screening with a patient?
Patients aged 50 to 80 years with a more than 20 pack-year smoking history who currently smoke or quit within the past 15 years should be considered for screening and have a discussion with their primary care provider. To figure out your pack years, multiply how many packs a day (assuming 20 cigarettes per pack) you smoke by how many years you have smoked.
If you are unsure if you meet this criteria, consult your provider.
What occurs during the lung cancer screening?
The patient undergoes a low-dose CT (LDCT) scan of the chest, which takes only a few minutes and does not require needles or contrast. The scan is interpreted using standardized protocols by our radiologist and will be reported to your primary care or ordering provider when completed.
If a patient is nervous to go alone, can they bring someone with them?
Absolutely! Patients may bring a support person to the appointment if desired. We always want to make sure our patients have the best experience possible.
Is it safe to have this screening regularly? What about radiation exposure?
Annual LDCT screening is considered safe for eligible patients, with radiation exposure kept low (typically less than 1.5 mSv per scan). The risk of radiation-induced cancer is very small compared to the benefit of early lung cancer detection in high-risk individuals.
What happens following the screening?
After your ordering provider receives and reviews the imaging study, they will decide the best next steps. Sometimes this is simply repeating your scan in the recommended screening interval, or they may refer you to Parkview’s Lung Nodule Clinic for further evaluation and monitoring.
If something is found, what are the next steps?
Findings are reviewed by a multidisciplinary team. Most nodules are benign and may require only follow-up imaging. But suspicious findings prompt further evaluation. The timeline for follow-up depends on the size and characteristics of the nodule, with urgent action for highly suspicious findings. This path could mean urgent follow-up with our Lung Nodule Clinic and/or other specialists determined by the imaging findings.
Are there things a patient can do now to reduce their risk of lung cancer?
The most effective way to reduce lung cancer risk is to stop smoking, avoid secondhand smoke, and reduce exposure to radon and occupational hazards that may damage the lungs. Generally speaking, it’s best to take steps to maintain overall lung health.
