BTS guidance for a pulmonary nodule

BTS refers to the British Thoracic Society. The guidance provides a structured pathway, but the chosen plan still depends on the complete clinical picture and discussion with the patient.

Clinicians review the nodule's size, volume, density, outline, position and appearance, along with factors such as age, smoking history, emphysema and previous cancer. Some clearly benign patterns require no further action, while indeterminate nodules need a defined assessment plan.

Repeat imaging can measure growth or confirm stability. Depending on the estimated risk and whether the nodule changes, the pathway may lead to continued CT monitoring, functional imaging, biopsy or a specialist surgical opinion.

Confirm the nodule's measurements, whether it is solid or subsolid, and the timing of the next scan. Supply older chest scans if they were performed elsewhere, because direct comparison may change the recommendation.

Attend the planned appointment even if you feel well; small nodules often cause no symptoms. If you smoke, ask for practical support to stop, which benefits lung and general health regardless of the nodule's cause.

Tell your healthcare team about a persistent or changing cough, coughing up blood, unexplained weight loss, chest pain or increasing breathlessness. These symptoms need clinical assessment rather than waiting for routine surveillance.

Call emergency services for severe difficulty breathing, a large amount of coughed-up blood, fainting or sudden intense chest pain.

Ask which nodule features determined your pathway, whether a risk calculator was used, how growth will be measured, what the next scan is intended to clarify, and under what circumstances a biopsy would be considered.
