Dual Commonwealth Games gold medalist Kerryn McCann has died after losing her second battle with cancer.The 41-year-old from Coledale passed away early this morning.McCann leaves behind her husband, Greg, and three children, Josie, 4, Benton, 10 and Cooper, 1. The champion marathon runner successfully fought her first health battle in 2007, after surgeons removed a cancerous tumour from her breast. She began chemotherapy in September that year and by May had thrown away her wig and resumed her rigorous jogging routine.``There was a time I thought I would die, that I would never see my children grow up,'' she told the Mercury earlier this year.``I am happy and relieved to be able to pull on a pair of running shoes again, but cancer changes your priorities.''But four months ago, Mr McCann confirmed that his wife was again being treated by doctors, this time for a secondary cancer in her liver. Sadly it was a battle she did not win. McCann and Jane McGrath, wife of the Australian fast bowler Glenn, supported each other through their cancer battles.Mrs McGrath died in June.
