Pancreatic cancer has been found to be "four separate diseases" not just one, according to new research.
Scientists at the University of Glasgow discovered the disease could be classified as one of four different sub-types, paving the way for more accurate diagnosis and treatment in future.
Professor Sean Grimmond said the ability to identify different sub-types of the disease could lead to more effective treatment for patients.
He said: "This study demonstrates that pancreatic cancer is better considered as four separate diseases, with different survival rates, treatments and underlying genetics.
"Knowing which sub-type a patient has would allow a doctor to provide a more accurate prognosis and treatment recommendations."
