Lung cancer. Coloured computed tomography (CT) scan of a large cancer tumour (upper left) that has spread to the lung in a 52-year-old woman with breast cancer. This scan shows a vertical "slice" through the patient's chest,created by a computer that combines multiple X-rays taken from different angles. The black areas correspond to healthy lung tissue. Cancer can spread to the lungs when malig- nant cells enter the bloodstream. The cells pass through the heart and are carried into the lungs,where they become trapped by narrow blood vessels and continue to multiply. Secondary tumours in the lungs dramatically reduce the patient's chance of survival | |
