Mesothelioma lung cancer. Left to right: computed tomography (CT) scan, coloured positron emission tomography (PET) scan and composite image of the thorax and abdomen. This patient has a malignant pleural mesothelioma (dark grey on CT scan, bright orange/purple on PET scan) in the right lung. This is a cancerous tumour in the lining of the lungs (mesothelium), caused by exposure to asbestos. Asbestos is a soft crystalline material that was used in construction and insulation. Many people exposed to asbestos dust develop lung cancers and disorders several years later. Asbestos is now banned, but it is still present in some old buildings.
