TV presenter Dermot Murnaghan has died aged 68. The veteran broadcaster and former Sky News presenter, announced that he had been diagnosed with stage four prostate cancer in June, telling followers that he was “responding positively” to treatment.Prostate cancer is entirely curable if caught early through a routine PSA test. However, Murnaghan’s cancer was too advanced for doctors to treat his prostate alone. “It blindsides you,” Murnaghan said of his diagnosis. “It was coming up to Christmas and the children were all coming home. It’s like a gut punch. I can only imagine the effect on them.”Following his diagnosis, Murnaghan subsequently began work as an ambassador for Prostate Cancer Research in a bid to increase public awareness of the need for screenings for high-risk groups.“If only I had got diagnosed at an earlier stage, all that hurt and worry I could have saved them,” he said. “I can’t take it away, but they are coping really well. They’ve been beyond excellent to me.”
