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'.
