Kylie Minogue has said that she sometimes wonders what a mother would be like, but has accepted that this will never happen.
The Australian pop star, 50, said that her breast diagnosis in 2005 "changed everything" over the course of her life, and that she tried not to dwell on "regret" outside of her successful music career.
Singer and actress Minogue, who was 36 when she was informed that she had the disease, told Sunday Times Style that she had learned to accept what had happened and "to continue".
Regarding the timing of the diagnosis and how it affected potential parenting, she said: "Realistically, you are on the late side of things. And although that was not on my agenda at the time, it changed everything.
"Of course I don't want to dwell on it, but I wonder what that would have been like."
She added: "Everyone will say that there are options, but I don't know, I am now 50 and feel more comfortable in my life.
"I can't say there is no regret, but it would be very difficult for me to continue if I classified it as a regret, so I just have to be as philosophical as I can."
Minogue also acknowledged earlier "mistakes" in her love life.
Before her relationship with GQ creative director Paul Solomons, who she said "feels good", Minogue dated French actor Olivier Martinez, British actor Joshua Sasse and the late INXS star Michael Hutchence.
She was engaged to Sasse, 31, until their split in 2017.
Minogue spoke with the magazine for a big summer in which she will perform in Glastonbury.
She will enter the stage in the Legend slot, 14 years after breast cancer diagnosis forced her to withdraw from her previously planned performance at the festival.
"I'm determined to cry – it's going to happen," she said about the show.
"When I had to be there, I looked from Australia, I had much bigger things then, but when I am there it will take me back to when I was not there, but I will continue to work."
