Despite being a mega-watt celebrity of her time, Newton-John was known as a “wonderfully unselfconscious star.” Her reputation was one of positivity and sincerity—core traits that shaped not only her personal life, but also her strategy for her coping and healing following her diagnoses. “If you think positive thoughts, you’ll create a positive world around yourself and attract positive people to you,” the actress told Us Weekly in 2019 following her third breast cancer diagnosis. In 2010, she shared a similar message while speaking with EmpowHer: “Not everybody is as fortunate… I realize that and I am very grateful that I am, but that positive attitude does really help in how you go through the journey.”

Asked for an update on her condition in 2021, the singer told Us Magazine: “I feel really well, thank you. Thanks to my husband and his plant medicine. I’m doing really well.” She added, “Plant medicine has been incredibly healing for me, but I think it’s just keeping a positive attitude and believing that I will be OK… is probably the most important part.” For more health news sent directly to your inbox, sign up for our daily newsletter. In a 2020 interview for the launch of her foundation (via Prevention), Newton-John shared that her cancer nearly went undetected following her initial screening. “I knew immediately that something was wrong. I had a mammogram and the mammogram was benign and then I had a needle biopsy that was also benign,” the Physical singer recalled. “And I don’t say this to scare women, but you just have to trust your instincts,” she said. Upon receiving her results, she decided to pursue further testing, including a surgical biopsy—a more invasive procedure in which the doctor makes an incision and removes tissue from the area in question, rather than just cells. This revealed cancer in her right breast, which would require the star to undergo a mastectomy and nine months of chemotherapy. “All of this was overwhelming,” the Grease star said. “It was a feeling of dread and terror of the unknown.” Ultimately, she used her own harrowing diagnoses to help “find a world beyond cancer” for others, she shared via the foundation’s website. “The whole experience has given me much understanding and compassion, so much so that I wanted to help others going through the same journey.”
