Olivia Newton-John shares health update amid stage 4 breast cancer battle

Music icon Olivia Newton-John says she is "doing well" amid her fight against breast cancer.

The 72-year-old singer gave the health update during a recent interview with Hoda Kotb on the Today show. 

"I'm winning over it well and that's how I see it," the much-loved Australian said.

"I don't think about it a lot, to be honest. Denial is a really good thing and I'm getting stronger and better all the time! I'm doing well!"

During the interview, the 'Physical' singer explained that right now, she's "feeling pretty good," managing her pain with medical marijuana.

"I have my days, I have my pains, but the cannabis that my husband grows for me has been such a huge part of my healing, and so I'm a really lucky person," she told Kotb.

Newton-John was first diagnosed in 1992 and overcame cancer again in 2013.

In May 2017, she was told the cancer had metastasised and spread to her bones.
