With a career spanning more than five decades, multiple cancer diagnoses followed the award-winning singer and actress through several of them.

Newton-John was first diagnosed with breast cancer in 1992 and underwent a partial mastectomy and reconstruction. She was diagnosed with breast cancer again in 2013. Then in 2018, she revealed doctors had found a tumor in her lower back. 

"It’s probably something I’ll deal with the rest of my life. But I will and I’ll be fine and there have been a lot of women, who have had reoccurrences, and continue on with their lives to be old ladies. That’s my vision," she told Australia’s 60 Minutes in 2017.

"I’ve had and I’m having an amazing life. So I have no complaints. I really don’t ... everyone goes through something. We all have something we need to go through in life and this has been my challenge," she added.

In 2021, she told People Magazine she was "feeling great" and had a lot to look forward to as the year went on, including the wedding of her daughter, Chloe Lattanzi, as well as releasing a new duets album.

Throughout her health challenges, Newton-John had been vocal about easing her symptoms with medical marijuana.
