Olivia Newton-John fought secretly against a second attack of breast cancer in 2013.
The 69-year-old superstar, who is currently fighting cancer for the third time, made the emotional disclosure in an interview with Channel Seven's Sunday Night.
Explaining why she chose not to make the diagnosis public at that time, the Grease actress told the program: "I thought, It's my life, and I decided to save it for myself."
In early 2013, Olivia was involved in a minor car accident, and a bulge appeared on her right shoulder.
She told Sunday Night that she initially believed it was due to the tension in her seatbelt, before the scanners revealed it was the return of breast cancer she had defeated two decades earlier.
It was an incredibly moving moment for the Xanadu singer, whose older sister, Rona, died of brain cancer at the same time.
