Olivia Newton-John has been diagnosed with cancer for a third time.
The Grease legend, 69, revealed her breast cancer spread to the base of her spine last year.
The shock diagnosis comes five years after her secret second battle with cancer and two decades after she first overcame the disease in 1992.
“My husband’s always there, and he’s always there to support me, and I believe I will win over it and that’s my goal,” she told Australian TV’s Sunday Night .
The actress – who is most famous for playing Sandy in 1978 musical Grease – is using homegrown cannabis as part of her treatment to fight the disease.
Her husband John Easterling runs the Amazon Herb Company which grows cannabis at their ranch in California.
“In California, it’s legal to grow a certain amount of plants for your own medicinal purposes,” she said.
“I’m very lucky that I live in a state where it’s legal and that I have a husband that is a plant-medicine man.”
She has also completely cut sugar out of her diet and is using more common medicines as well.
In December the singer first revealed she was taking dope to ease the pain of agonising breast cancer .
She drinks a cannabis mixture made by her herbalist husband to control the illness.
Olivia said: “My husband’s a plant medicine man so he grew cannabis and made tinctures for me for pain and inflammation.”
She said it made sense to use the “magical, miracle plant” instead of popping pills and applying steroid creams. She said: “It helped me a lot with pain because I don’t like taking prescription drugs.
“It’s kind and compassionate. It’s what should be available for everybody to use.”
Olivia was first diagnosed with breast cancer in 1992 and had a partial mastectomy and chemotherapy.
In May 2017 she had a painful back caused by the cancer spreading to her lower spine.
She said: “The pain was the hardest thing. I can walk, but I can’t go long distances.”
But the star, who enjoyed having to slow down, is upbeat about fighting the illness and performing.
She added that the public have lifted her spirits.
