Primary lung cancer starts in the cells of the lung. The lungs are in the chest, one on each side of the heart. The right lung has 3 main parts, called lobes. The left lung is a bit smaller and has 2 lobes. The lungs are cushioned and protected by a thin covering called the pleura. The pleura has 2 layers of tissue. One layer covers the lungs and the other lines the inside wall of the chest. There is a small amount of fluid (pleural fluid) between the 2 layers of the pleura. The pleural fluid allows the layers to slide over each other as you breathe.
