Olivia Newton-John's daughter Chloe Lattanzi tackled her substance addiction "head-on" so she could help her mother through her cancer battle.

The 70-year-old actress was diagnosed with breast cancer for the third time last year, and her 33-year-old daughter - whom she has with ex-husband Matt Lattanzi - has opened up about her "fight" to stay sober and how she entered rehab so she could be "happy and bright" around her mum through her health struggles.

Appearing on TV show 60 Minutes Australia, Chloe - who has also suffered from anorexia - admitted: "We say we all have our cancers."

"You know, mine is my battle with addiction," she said during her interview.

"I have to keep myself sober the rest of my life and that’s a fight and it takes work. And we all have our cancers.

"I’m not trying to make her struggle sound small, I’m trying to say, I think it makes it easier to deal with when you go, 'Oh yeah, everyone has a cancer.'"

On her decision to go to rehab in 2013 and her "severe depression", Chloe said: "I wanted to be bright and happy and available and around for my mum when she was struggling with this and I thought I was okay but I wasn’t, I was still struggling with severe depression and I faced it head-on."

The singer-and-actress added how important it is to "deal" with "pain" and admitted it has made her a "better person".

She added: "There’s no more running away from your pain.

"Deal with it, she needs you. I feel it’s made me a much better person."

In the same interview with 60 Minutes reporter Liz Hayes, Olivia revealed how she's grappled with her cancer diagnosis.

"When you’re given a cancer diagnosis or a scary illness diagnosis, you are suddenly given a possibility of a time limit," she explained.

"If you believe the statistic, you’re going to make them happen. If somebody tells you, 'you have six months to live', very possibly you will – because you believe that."

"I’m so lucky that I’ve been through this three times and I’m still here. I’m living with it," she continued.

"Everyday is a gift now, particularly now."

Although Olivia has revealed that her cancer has metastasized to her bones, she admitted she isn't letting cancer hold her back, and said she is "doing well" despite her diagnosis.

She said: "I'm doing well. I'm thriving! This is my world."

The Grease legend has battled cancer on-and-off since 1994.
