“I am probably one of those people who's living beyond cancer, living beyond probably what people expected to happen,” the Australian singer said in her video.

She then got tearful recalling her 1992 diagnosis and said, “I knew immediately something was wrong.

“I had a mammogram. The mammogram was benign and I had a needle biopsy that was also benign,” Newton-John said. But she persisted and got a surgical biopsy, which then led to her breast cancer diagnosis.

The singer added: “I don't say this to scare women, but you have to just trust your instincts.

“All this was overwhelming. It was a feeling of dread, terror, the unknown,” she said of that time.

Newton-John then added she chose to be strong moving forward for the sake of her daughter, Chloe Lattanzi.

“I made the decision that I was going to be okay. I had to believe I was going to be okay, that my daughter was the most important thing in my life and I would be okay for her,” the Grammy winner said.

She also discussed her combination of cancer treatments ranging from chemotherapy, meditation, acupuncture, massage, and plant medicine to help her manage her pain.

Newton-John has long been an advocate for medicinal marijuana.

“Plant medicine has played an amazing role in my life. I have seen the incredible beauty of the plants and their healing abilities,” the actress said. “I know it sounds strange but if I hadn't had that experience, I wouldn't be sitting here talking to you about kinder therapies.”

She added: “Your body wants to heal itself. That's why I'm excited to start this foundation."
