Originally diagnosed with the disease in 1992, the iconic star revealed in 2017 that she was once again faced with a tough fight as her cancer returned and spread to her back.

Most recently, there was a rumor circulating that Olivia’s organs were "shutting down" and she was "clinging to life." However, the star’s niece, Tottie Goldsmith, told Channel Seven, "You can rest assured she is going nowhere and in really good health. A sick rumor." 

Olivia continued to fight her Stage 4 breast cancer diagnosis with a more holistic approach. According to her daughter, the singer uses a mixtures of herbs and cannabis to treat her symptoms. "My mom and best friend is going to be fine! She will be using medicine that I often talk about. CBD oil and other natural healing remedies plus modern medicine to beat this," Chloe reportedly said. "Cancer is the disease of our generation and it is part of my and my mother’s quest to beat this insidious monster."

Despite the diagnosis, Olivia remained positive. "I'm not going to be one of those statistics. I'm going to be fine," she told Today in 2017. "I think that you can live with cancer like you can live with other things, if you take care of yourself. ... It taught me I'm stronger than I thought I was. I think most people that go through cancer find that out about themselves."

The icon died on August 8, 2022, peacefully and surrounded by family and friends, according to her husband.
