Olivia Newton-John Postpones Tour After Breast Cancer Diagnosis
Stars Who Battled Breast Cancer

Olivia Newton-John announced she's "reluctantly postponing" her upcoming tour dates after learning the back pain she'd been dealing with "turned out to be breast cancer that has metastasized to the sacrum."

The singer made the announcement via her social pages on Tuesday morning.

"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," the statement from her camp explained.

"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," Newton-John added.

The "Grease" star was diagnosed with breast cancer back in 1992, underwent chemotherapy and had a partial mastectomy and reconstruction. She opened up the Olivia Newton-John Cancer Wellness and Research Centre in 2008.

"There will be no interview requests accepted at this time as Olivia's focus is on her treatment and healing," the statement added. "Ticket buyers for the upcoming concerts should contact venues directly about refunds. Rescheduled concert dates will be posted at OliviaNewton-John.com in the coming weeks."
