Singer and actress Olivia Newton‑John has revealed she has breast cancer again, 25 years after recovering from her original diagnosis.

The Grease star has postponed upcoming tour dates after discovering that severe back pain she has been suffering is a result of the disease spreading to her spine.

The 68‑year‑old was due to perform across the US and Canada next month.

She will have treatment and expects to return to the stage later in 2017.
