LOS ANGELES (REUTERS) - Grease actress and singer Olivia Newton-John said on Tuesday (May 30) that her breast cancer has returned and has spread to her lower back.
Newton-John, 68, who became an advocate for healthy living and medical research after her first bout with breast cancer in 1992, will undergo radiation treatment and is confident of returning to work later this year, her representatives said in a statement.
"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 said.
The statement said the Physical singer was postponing her June US and Canadian tours.
"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 metastasisd to the sacrum," Tuesday's statement said.
British-born and Australian-raised Newton-John started her career as a singer with pop hits like If Not For You and I Honestly Love You.
She shot to international fame in the 1978 movie adaptation of musical Grease, playing goody-goody teenager Sandy opposite John Travolta's wild boy Danny Zuko.
Newton-John was first diagnosed with breast cancer in 1992, and has raised funds for research and treatment as well as campaigning against animal cruelty.
