Kylie Minogue lives in fear of her breast cancer returning.
The '2 Hearts' singer, who began performing again late last year after battling the disease, revealed she is terrified she has relapsed every time she feels unwell or even has a headache.
Kylie, who was forced to tell fans on her 'Showgirl Homecoming' tour she was too ill to carry on after contracting a respiratory-tract infection earlier this year, said: "I was fresh out of treatment when we started that tour. I was terrified and really doubting whether I had made the right decision to go on the road in the first place. I relaxed as time wore on, but that was scary, that moment. And there have been moments since then.
"Your body, your muscles have a memory of the way it was when you were sick, and there are definitely times when I float back to that place. I had migraines a few weeks ago, and I just went, 'Yeesh - no, please.' "
The 39-year-old star - who went through a gruelling chemotherapy treatment after being diagnosed with the cancer in May 2005 - also revealed she plans to move to the country in a bid to "reclaim herself".
She added to Britain's Style magazine: "I do have this need to reclaim myself a little bit, to do things to make me feel whole, which is why I'm doing all these things such as horseback riding and taking walks in the country and looking for a place outside London to chill."
Kylie rubbished reports she has rekindled her romance with actor Olivier Martinez, but added he was "amazingly supportive" during her illness.
She said: "No, no, we've definitely split up. But I can't tell people enough how amazing and supportive and instrumental he was in getting me through that period and back on stage. And I did love his dog, Sheba. Oh, Sheba, she was the love of my life."
Meanwhile, the '2 Hearts' singer - whose chances of conceiving naturally were affected by the chemotherapy treatment she received for breast cancer in 2005 - is considering giving a home to an underprivileged child from her native Australia.
A source said: "She would make a great mother. She is so caring and considerate and has a playful sense of humour as well.
"Having cancer really got her thinking about her chances of having a child. She feels now might be the time to go ahead with adoption. She has a lot of love to give."
Kylie, who has been single since splitting from French actor Olivier Martinez in February, has been seeking advice about her adoption plans from her sister Dannii and her parents.
The 39-year-old singer recently admitted being diagnosed with breast cancer made her realise how much she wants to become a mother.
She said: "I love children. Always have and always will. But it's only since my cancer that I have given serious thought to having them".
Earlier this year, Kylie dismissed reports she was having an operation to improve her chances of conceiving naturally.
She said: "Contrary to some reports, I am not having all sorts of weird treatments to try and get pregnant. Instead, we will just have to wait and see what doctors say." |
