Lung cancer takes place in the cells of the lung when a cancerous (malignant) tumor grows and destroys nearby tissue. Lung cancer treatment is followed by a surgical procedure that removes all or part of a lung which further removes cancerous cells in the tissue. The cells in the lung sometimes change and no longer grow or behave normally. These changes result in non-cancerous (benign) tumors such as hamartoma and papilloma. But in some cases, changes into lung cells can cause cancer.
Lung cancers are classified into non–small cell lung cancer and small cell lung cancer based on the type of cell in which cancer started. Your surgeon works to remove the lung cancer and a margin of healthy tissue by the following procedures
- Lobectomy – removal any part of the lung
- Wedge resection – When a tiny section of lung that comprises of the tumor along with a margin of healthy tissue
- Pneumonectomy – elimination of the entire lung
- Sleeve resection – removal of a larger portion of the lung, but not an entire lobe
