What does a lung nodule biopsy mean?

Percutaneous lung biopsy is primarily used to detect pulmonary nodules or masses. When benign and malignant lesions cannot be reliably differentiated, further evaluation—particularly of peripheral pulmonary nodules or masses—is recommended. Specific indications are as follows:

1. Percutaneous lung biopsy. For intrapulmonary masses, not only is definitive diagnosis and differentiation between benign and malignant lesions required, but identification of the histopathological subtype in malignant cases is also essential to guide clinical selection of appropriate, targeted chemotherapeutic agents. Conventional noninvasive imaging studies often fail to meet these diagnostic requirements. Computed tomography (CT)-guided percutaneous fine-needle aspiration (FNA) combined with automated core needle biopsy* is commonly employed to obtain tissue specimens for pathological examination.

2. Lung biopsy. Percutaneous lung biopsy is a highly valuable invasive diagnostic and differential diagnostic tool for pulmonary and thoracic diseases. It is indicated for distinguishing benign from malignant pulmonary and thoracic tumors, as well as for determining the nature of pulmonary nodules and differentiating among potential etiologies.

After undergoing biopsy, patients should wait two hours before eating and then take anti-inflammatory medications as prescribed by their physician to prevent wound infection. Dietary modifications are also advised: avoid spicy and irritating foods, and instead consume more fresh vegetables and fruits.
