“We know we’re gonna die at some point and we don’t know when it is,” she reasons. “When you’re given a cancer diagnosis or a scary honest diagnosis, you’re suddenly given a possibility of a time limit. The truth is, you could get hit by a truck tomorrow. So every day is a gift, particularly now.”

Newton-John survived a bout with breast cancer in 1992, and again in 2013. She was diagnosed again in May of 2018, and she found out it had spread to her back, forcing her to cancel tour dates and seek alternative forms of treatment. In January of 2019, the singer turned to Twitter to welcome the new year by refuting tabloid reports that she was "clinging to life."

She tells 60 Minutes Australia that she's "back to full force again," adding that she believes she can beat her disease again with a range of alternative treatments that include herbs, medical cannabis and meditation. The singer, who scored a string of country hits in the 1970s that included "Let Me Be There," "If You Love Me (Let Me Know)," "I Honestly Love You," "Please Mr, Please" and more before making the move to pop stardom, says she's not interested in doctors' predictions about how long she has to live. She sees her death as "a long way away."

“If you believe the statistics, you're going to make it happen," she states. "If somebody tells you you have six months to live, very possibly you will because you believe that. So for me, psychologically, it’s better not to have any idea of what they expect or what the last person that has what you have lived, so I don’t tune in. It’s just better for me. ”
