A £14m study to track the development of tumours in lung cancer has been launched in Aberdeen.
Experts from Aberdeen Royal Infirmary will track how lung tumours develop and evolve in real time as patients receive treatment.
Researchers in Birmingham, Cardiff, Leicester, London and Manchester are also taking part in the project.
About 850 patients will be monitored to see how cancer mutates if it returns.
