Lung cancer is a malignant tumour that starts in the cells of the lung. Malignant means that it can spread, or metastasize, to other parts of the body. When cancer starts in lung cells, it is called primary lung cancer. The lung is part of the respiratory system. You use your lungs when you breathe.
Lung cancer starts in the cells lining your lungs. Cancer cells. grow faster and look abnormal in comparison with your healthy. cells. The cancer cells continue to grow and eventually can be. seen as a tumor on imaging tests. The cancer cells can spread. (metastasize) to other parts of the lung and body. The stage of. your cancer is determined by the size of the tumor and if there. is spread to other areas. These areas include nearby lymph. nodes and the mediastinum (area between the lungs).
