Singer Kylie Minogue says she wonders what having children might have been like after her breast cancer battle ruined her chances of being a mother.The Australian pop star, 50, said she did have some regrets, but had accepted that she would not become a mother, reports thesun.co.uk.Minogue was diagnosed with breast cancer in 2005 at the age of 36. She told Sunday Times Style magazine: "Realistically, you're getting to the late side of things. And, while that wasn't on my agenda at the time, it changed everything."I don't want to dwell on it, obviously. But I wonder what that would have been like. Everyone will say there are options, but I don't know. I'm 50 now, and I'm more at ease with my life."I can't say there are no regrets, but it would be very hard for me to move on if I classed that as a regret. I just have to be as philosophical about it as I can," Minogue said and added, "You've got to accept where you are and get on with it."
