London: Singer Kylie Minogue says she used to worry about her live performances until she battled and beat breast cancer.
The 44-year-old pop superstar, who was diagnosed with the disease in May 2005, said when she was given the all clear from the illness in 2006 she also gained a new confidence in her abilities as an artist, reported Digital Spy.
"Even with the `Fever` tour [in 2002], as proud as I was of that tour, I was still a little uncertain on stage. It probably wasn`t until after being ill, coming back onto the road after the `Showgirl` tour stopped.
"I thought, `I just can`t worry that much, people are enjoying it, I love doing it, so I owe it to myself to try and enjoy it and let go.` In anything you do, the more relaxed you are the better you will be. That`s what I try to do," she said.
Minogue, who cried on stage when she resumed the `Showgirl` tour in November 2006, in Australia, said she always had concerns about the strength of her vocal abilities because she only became a pop star after having a successful acting career in the soap opera `Neighbours`.
