Recent research has revealed that the majority of deaths from prostate cancer are due to the cancer itself.
The team from King's College London looked at 50,667 men with prostate cancer over the course of a decade.
Over this time period a total of 20,181 men died. Of these, 49 per cent died as a result of the cancer itself.
Around 12 per cent died due to other cancers, 17 per cent died because of heart disease, eight per cent from pneumonia and 13 per cent due to other causes.
Professor Henrik Moller, study author from King's College London and head of analysis and research at the NCIN, said: "Our data show that a high proportion of men with prostate cancer die from the cancer.
"Our findings challenge the commonly held view that most men with prostate cancer will die with the disease rather than from it."
