Kylie Minogue compared her breast cancer operation to going on stage.
The 45-year-old singer - who was diagnosed with the disease in May 2005 - found the preparation for going under the knife felt "familiar" to her, likening it to getting ready for a concert.
Speaking to Radio Times magazine, her friend Kathy Lette recalled a conversation in which Kylie said:
"When the cancer was diagnosed and I was going in for surgery, I was lying there on the trolley and I was suddenly taken by the fact that I was going into a theatre.
"Medicine is so different from my business, but in some ways, so similar. The whole gowning up, the masks, the build-up, the adrenaline... It all felt so familiar.
"I was under lights. Ah! There's my spotlight." Kylie, who was given the all-clear from cancer in 2006, has previously admitted battling the disease stopped her worrying about her live shows.
She 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. 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."
