LOS ANGELES • Grease actress and singer Olivia Newton-John said on Tuesday 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 of breast cancer in 1992, will undergo radiation treatment and is confident about 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," she said.
The statement said she was postponing her tours this month of the United States and Canada.
"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 metastasised to the sacrum," Tuesday's statement said.
British-born and Australian-bred 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 the musical Grease, playing goody- goody Sandy opposite John Travolta's wild boy Danny.
She has raised funds for cancer research and treatment.
