Introduction
Surgery is recommended when the diameter of a pulmonary nodule reaches or exceeds 8 mm. When a lung nodule is 8 mm or larger in diameter, doctors begin to consider the possibility of surgical intervention. This is because larger nodules are more likely to have malignant characteristics or may already be affecting lung function. Patients should consult a specialist physician and follow medical advice when deciding whether to proceed with surgery.
Generally, surgery is recommended when the diameter of a pulmonary nodule reaches or exceeds 8 mm. The detailed analysis is as follows:
When the diameter of a pulmonary nodule reaches or exceeds 8 mm, doctors begin to consider the possibility of surgical intervention. This is because larger nodules are more likely to have malignant characteristics or have already affected lung function to some extent. In particular, when the nodule measures between 10–15 mm and imaging features suggest a high likelihood of malignancy, or when a non-surgical biopsy confirms malignancy, surgery is usually necessary. For nodules measuring 15–30 mm in diameter, regardless of imaging features or clinical presentation, there should be a high suspicion for malignancy, and surgical treatment is generally recommended, followed by pathological examination to confirm the diagnosis. When the nodule exceeds 30 mm in diameter, the probability of malignancy increases significantly; even in the absence of clear malignant signs, prompt surgical removal is advised.
When deciding whether to proceed with surgery, patients should consult a qualified physician and follow medical advice. Additionally, maintaining healthy lifestyle habits and undergoing regular physical examinations can help prevent and manage pulmonary nodules.
