Australian singer Dannii Minogue has changed her lifestyle in the wake of her sister KYLIE's breast cancer diagnosis.

The pop beauty was so terrified when her elder sibling underwent two operations in May (05), she quickly made changes in her diet and fitness regime to reduce her chances of falling ill.

She says, "Kylie is doing great at the moment but the whole thing has made us reassess our lives.

"We never take anything for granted and really go all out to look after ourselves health-wise. I have always been health-conscious but now am even more so."
