Grease icon Olivia Newton-John has been diagnosed with cancer for the third time in three decades. “I’m one of millions in this fight…in this journey,” the actress, 69, explained on the Australian show Sunday Night on Sunday, September 9. “A lot of people see it as a fight, and [however] you choose to see it, that’s your prerogative. …I see it as part of my mission.”  She also declared, “I believe I will win over it.”

She says doctors found a tumor in her lower back in 2017. “I’m still treating it, and I’m treating it naturally and doing really well,” she said, adding that she’d cut sugar out of her diet, gone through radiation and is treating the pain with cannabis oil.

Newton-John was diagnosed with breast cancer in 1992, and then again in 2013. She has become a leader in the push for cancer research and screening. Newton-John says she is keeping her chin up. “I’m a very privileged person, and I’m very aware of that,” she says. “I have a wonderful husband, I have all the animals I adore, I have an incredible career. I have nothing really to complain about.”
