Olivia Newton-John revealed that she has been diagnosed with cancer for the third time in three decades.  The 69-year-old announced the news in an interview with Australia’s Channel Seven on Sunday, saying that cancer has returned to her back, where she has a tumor at the base of her spine.  Newton-John, whose career has spanned from her breakout role in “Grease” to a decades-long, internationally renowned singing career, has battled cancer twice before. She revealed in the interview for the first time that along with her initial 1992 breast cancer diagnosis, doctors found cancer in her shoulder after she was involved in a car accident in 2013.

The interview unveiled that Newton-John is eating healthily and undergoing radiation treatment to treat her cancer and taking cannabis oil for pain relief.  Newton-John said she decided to keep her second bout of cancer to herself.  “The first time I talked about it, and the second time I thought I didn’t really need to share this, it’s not something I need to share with people,” she said. “It’s my life and I decided to keep it to myself.”  Outside of her own battles with cancer, the disease has struck another member of her family: Her sister died six weeks after being diagnosed with an aggressive form of brain cancer in 2013.
