When should you follow-up a lung nodule?

For multiple solid pulmonary nodules that are 6 mm or larger, initial follow-up at 3–6 months is required, regardless of the risk factors. For low-risk patients, the guidelines suggest an optional additional follow-up at 18–24 months.

Do lung nodules need to be monitored?

Why is it important to monitor pulmonary nodules? Most pulmonary nodules are not cancerous. If a nodule is an early developing cancer, it has the best chance of being cured if it is detected and treated as early as possible.

How do you monitor lung nodules?

Computed tomography is the imaging modality of choice to reevaluate pulmonary nodules seen on chest radiography and to follow nodules on subsequent studies for change in size.

What do cancerous nodules look like?

They appear as round, white shadows on a chest X-ray or computerized tomography (CT) scan. Lung nodules are usually about 0.2 inch (5 millimeters) to 1.2 inches (30 millimeters) in size. A larger lung nodule, such as one that’s 30 millimeters or larger, is more likely to be cancerous than is a smaller lung nodule.

Can a lung nodule be found on a CT scan?

A lung nodule (or mass) is a small abnormal area that is sometimes found during a CT scan of the chest. These scans are done for many reasons, such as part of lung cancer screening, or to check the lungs if you have symptoms.

When do you need a CT scan for lung cancer?

They are more often the result of old infections, scar tissue, or other causes. But tests are often needed to be sure a nodule is not cancer. Most often the next step is to get a repeat CT scan to see if the nodule is growing over time.

How does follow up work on lung cancer screening?

A system-wide tracking mechanism for previously identified nodules in need of follow-up is a safety net for ensuring follow-up. If a follow-up is overdue then an outreach call to the provider can be performed and follow-up tracked from there as well.

How often should you have a pulmonary nodule scan?

For multiple solid noncalcified nodules with at least one nodule 6 mm or larger in diameter, follow-up is recommended at approximately 3–6 months, followed by an optional second scan at 18–24 months that will depend on estimated risk. (grade 1B; strong recommendation, moderate-quality evidence).
