Olivia Newton-John has revealed to her fans that she has been diagnosed with breast cancer.
The 68-year-old recently had to cancel her Canadian tour due to back pain, but in a statement released last night, her manager said that "turned out to be breast cancer that has metastasized to the sacrum."
The statement read: "Olivia Newton-John is reluctantly postponing her June U.S. and Canadian concert tour dates.
"The back pain that initially caused her to postpone the first half of her concert tour, has turned out to be breast cancer that has metastasized to the sacrum.
"In addition to natural wellness therapies, Olivia will complete a short course of photon radiation therapy and is confident she will be back later in the year, better than ever, to celebrate her shows.
Olivia added: "I decided on my direction of therapies after consultation with my doctors and natural therapists and the medical team at my Olivia Newton-John Cancer Wellness and Research Centre in Melbourne, Australia."
The Grease superstar was previously diagnosed with the disease in 1992.
We wish her a speedy recovery.
