A lobectomy is a type of lung cancer surgery in which one lobe of a lung is removed because it contains malignant tumors. A lobe is one of the sections that make up each lung. The right lung has three lobes, and the left lung has two.A lobectomy is also occasionally performed for other conditions, such as tuberculosis, severe COPD, or trauma that interrupts major blood vessels near the lungs.There are two main types of lobectomy procedures. Deciding whether one of these surgeries is the right course of treatment for you means understanding the preparation needed, the recovery process, possible complications, and prognosis after a lobectomy.
