Does a pulmonology perform low-dose CT lung screening?

The exact pathway varies by facility. A pulmonologist may assess whether screening is appropriate, explain possible benefits and harms, review the report, and arrange follow-up for a finding that needs further evaluation.

Low-dose CT uses X-rays to create detailed pictures of the lungs with less radiation than a conventional diagnostic chest CT. It is intended for people without lung cancer symptoms who meet a screening programme's eligibility criteria. The scan can reveal small lung nodules, but a nodule is not the same as a cancer diagnosis.

A radiologist reads the images and categorises any findings. The next step may be routine screening later, an earlier repeat scan, comparison with older images, or referral for additional assessment. Some findings outside the lungs may also need discussion with the appropriate clinician.

Contact a screening service or pulmonology clinic and provide an accurate smoking history, your current symptoms, previous cancers, and any earlier chest imaging. Eligibility depends on the programme and personal risk factors. Bring prior scan reports or images when available, because comparison can help the radiologist assess whether a finding has changed.

Screening is designed for people without symptoms. New coughing up of blood, severe or worsening breathlessness, chest pain, fainting, or blue-grey lips calls for urgent medical assessment rather than waiting for a screening appointment. A persistent cough, unexplained weight loss, recurring chest infections, or a change in breathing should be evaluated clinically so the team can choose a diagnostic pathway.

Ask which eligibility criteria apply to you, whether old scans are needed, how results will be delivered, and who will coordinate any follow-up. Discuss the chance of findings that require repeat imaging even though they are not cancer, as well as the cumulative radiation exposure from continued screening.
