Olivia Newton John has been battling cancer for the second time and she's doing her best to help other cancer suffers while she fights her own battle.
Olivia spoke to Today show host Natalie Morales while the two visited the Olivia Newton-John Cancer Wellness & Research Centre in Melbourne.
Olivia, 68, explained that before learning she had cancer for a second time in May of this year, she initially thought she had sciatica – pain radiating along the sciatic nerve which runs down the leg from the back.
"It was painful to walk, so I thought that it was that," she told host.
"I was still performing. I would kind of a grit my teeth and take a couple of aspirin and go on."
She was first diagnosed with breast cancer in 1992 and after eight months of chemo and a patial mastectomy she was cleared.
Then in May this year she was shocked to learn that she had cancer at the base of her spine.
"In my mind, it was over. I'd finished with it," she said.
Olivia underwent radiation treatment on her sacrum, and by that point the pain was so was so debilitating she could barely walk.
She was then introduced to medicial marijuana by her husband to help her heal.
"People have this vision from the 60s of people just sitting around, you know, getting stoned. It's not about that. This plant is a healing plant," she explained.
"I think we need to change the vision of what it is. Because it helped me greatly. And it helps with pain and inflammation."
"I'm not going to be one of those statistics. I'm going to be fine. And I will probably deal with this in my life as an ongoing thing," she said. "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," she said.
