“A blood test for men with prostate cancer could detect if the illness is likely to be life-threatening,” the Daily Mail has reported. In some cases prostate cancer can be benign, but in others it can be life-threatening and require treatment such as surgery or chemotherapy.
The news is based on research that looked at whether scanning for genetic abnormalities in various types of tissue could be used to predict whether prostate cancer would rapidly relapse after treatment. To conduct the research, scientists looked at samples of blood, prostate tumours and healthy prostate tissue from 238 men who had undergone surgery to remove their whole prostate gland. They compared genetic differences to the different outcomes the men experienced.
