Kylie Minogue stopped worrying about her live concerts after she beat breast cancer.

The 44-year-old pop superstar was diagnosed with the potentially killer disease in May 2005 and she has revealed when she was given the all clear from the illness in 2006 she also gained a new confidence in her abilities as an artist.

Kylie - who had to abandon her 'Showgirl: The Greatest Hits Tour' in 2005 after she discovered she had cancer - said: ''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 certainly wasn't 100 per cent, but by that point I just thought, 'f**k it'. 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.

''Well, that's the idea anyway. I'll still get stressed about a show, but it was around then that I started to accept who I am. This is who I am, this is where I'm good, this is where I'm not so good, this is my voice.''

Kylie - who cried on stage when she resumed the 'Showgirl' tour in November 2006, in Sydney, Australia - admits 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'.

She explained to ''As far as live shows go, I still had that monkey on my back from the very beginning about my voice. Aside from it getting better over the years, and me learning how to use it, and having trained myself and knowing technically what to do, I had to accept it before I could let it be.''
