| ==Overview==
| |
|
| |
| Biopsy for lung mass may be classified into 2 categories: non-surgical biopsy and surgical biopsy. Biopsy findings associated with lung mass will depend on tumor [[histology]]. Common types of lung tissue biopsy for pulmonary mass, include: conventional bronchoscopic-guided transbronchial biopsy, bronchoscopic-transbronchial needle aspiration, endobronchial ultrasound-guided sheath transbronchial biopsy, and endobronchial ultrasound-guided transbronchial needle aspiration. Common indications for biopsy in lung mass, include: suspected lung cancer, malignant features (lymph node involvement).<ref name="pmid15347106">{{cite journal |vauthors=Podbielski FJ, Rodriguez HE, Brown AM, Blecha MJ, Salazar MR, Connolly MM |title=Percutaneous biopsy in evaluation of lung nodules |journal=JSLS |volume=8 |issue=3 |pages=213–6 |year=2004 |pmid=15347106 |pmc=3016799 |doi= |url=}}</ref>

| ==Surgical Biopsy==
| |
|
| |
| *Surgical excision is the mainstay therapy for malignant lung mass
| |
| *Surgical excision is also the primary choice for the definitive diagnosis of malignant lung mass
| |
| *In lung mass, surgical procedure selection will depend on the size, margins, and size of the tumor.
| |
| *Common surgical procedures for the treatment of lung mass, include:
| |
| :*Wedge resection
| |
| :*Lobectomy
| |
| :*Segmentectomy
| |
| :*Lung volume reduction surgery
