Lung cancer in the upper lobe of the left lung has both peripheral and central type. The localization range of lung cancer in the upper lobe of the left lung is relatively large, and only lung cancers below the segmental bronchus are peripheral lung cancers, so not all lung cancers in the upper lobe of the left lung are necessarily peripheral type. If peripheral lung cancer can be operated, it should be aggressively operated and resected. Comparatively speaking, peripheral lung cancer is farther away from large blood vessels and bronchial tubes, which is safer. As it can reach a better surgical scope and the lesion itself has less influence on respiratory function, peripheral lung cancer can often get better curative effect. Therefore, not all left upper lung cancers are peripheral type, but peripheral type has relatively better curative effect.
