Olivia Newton-John postpones tour dates due to breast cancer

Singer-actress Olivia Newton- John has announced that she is "reluctantly" postponing her next month's concert tour dates in Canada and the United States.
In a statement, the four-time Grammy award winner posted on social media, she said the back pain that initially caused her to postpone the first half of her tour has turned out to be breast cancer that has metastasised to the sacrum.
In addition to natural wellness therapies, the 68-year- old will complete a short course of photon radiation therapy.
"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 singer said.

The "Grease" star was first diagnosed with breast cancer in 1992-the same weekend her father died of cancer. She underwent a partial mastectomy, chemotherapy and breast reconstruction.
In 2008, she built the Olivia Newton-John Cancer and Wellness Centre in Melbourne, Australia.
The singer had been on tour to promote the album LIV ON, a collection of songs about overcoming trauma, like her battle with breast cancer and the loss of her sister to brain cancer.
