Surgery is an operation to remove the cancer. The type of surgery a doctor performs depends on the location of the tumor in the lung. An operation to remove only a small part of the lung is called a segmental or wedge resection. When the surgeon removes an entire lobe of the lung, the procedure is called a lobectomy.
Pneumonectomy is the removal of an entire lung.
Chemotherapy is the use of anticancer drugs to kill cancer cells throughout the body. Even after cancer has been removed from the lung, cancer cells may still be present in nearby tissue or elsewhere in the body. Chemotherapy may be used to control cancer growth or to relieve symptoms. Some anticancer drugs are given in the form of a pill. Radiation therapy, also called radiotherapy, involves the use of high-energy rays to kill cancer cells.
