Sarah Harding is taking cannabis oil to ease pain amid her cancer battle after Blue’s Duncan James said it would help

SARAH Harding says she's taking cannabis oil to her ease pain as she struggles on with her brave cancer battle.

The Girls Aloud star revealed her pal Duncan James from boyband Blue said it could help.

Sarah, 39, wrote in her recent autobiography Hear Me Out: "He’d used it after he suffered a massive back injury, while he was doing drag and wearing heels in Priscilla, Queen Of The Desert.

"I figured that if it was something that could help Duncan in that situation, then I should definitely give it a go."

Sarah has advanced breast cancer and was rushed to intensive care with sepsis where she spent a fortnight in a coma that left her unable to speak for weeks.

Sarah thought chemotherapy was working until the secondary tumour destroyed her hopes.

She is refusing radiotherapy treatment on her skull for a secondary tumour because she does not want to lose her hair — with no health guarantees at the end of it.

She says she is grateful just to wake up every day because she now realises just how precious life is.

The singer does not know exactly how long she has left — and does not want to know. She was told by doctors that last Christmas would “probably” be her last.

Since being ill, Sarah penned a book Hear Me Out, to urge other women to get checked over before it is too late.

Updating fans on Instagram earlier this year, Sarah wrote: "Hi everyone. Thank you so much for all the messages of love and support that I’ve received since my last post.

"Everyone has been so kind and reading your comments and DMs has been such a huge source of strength to me. I can’t deny that things are tough right now but I’m fighting as hard as I possibly can and being as brave as I know how."

Revealing how the book came to be, she continued: "In September the lovely people at Ebury Publishing asked me if I would be interested in writing a book about my life story."
