Olivia Newton-John is feeling grateful and enjoying "every day" amid her battle with cancer.
"Of course [I have fear]. I mean, everyone does. We're all going to die -- I mean, that's probably the hardest thing to accept as a human being," Newton-John said.
"I kind of consider I've had a gift of extra time."
"I'm very grateful. I'm 70 and I've had the most amazing life," she added. "I have extra time -- so whatever that is, I'm grateful for it and I'll just enjoy every day."
She confirmed there was a second bout with cancer in 2013 she kept secret from the public.
"Because of the speculation," the star explained.
The "Grease" star is undergoing hormone therapy, radiation and injections to strengthen her bones and taking herbs, supplements and medical cannabis, in addition to her positive outlook.
"[I'm] winning over [cancer]," the actress said.
"I think what you think creates your reality ... I try to always deal with it in a positive way."
Newton-John said in an Instagram video in January rumors of her death had been "greatly exaggerated."
She discusses her journey in her memoir, Don't Stop Believin', which debuts March 12 in the U.S.
