The 76-year-old confirmed she was battling the illness and has been in immense pain since the cancer spread to her hip.
Cornelia is best known for playing Alf Stewart’s sister Morag and has assured that she has every intention of retuning to Summer Bay.
“It’s a hard road, but we’ll get there,” she said during an appearance on Australia’s Current Affair.
“I’m feeling fine, albeit what’s inside me. I’m really feeling ok. The pain comes and goes but you expect that.
“It’s par for the course. We’re gonna fight it, by god I am.”
The Liverpool-born actress has played Morag on and off for over 20 years and was last seen in Home and Away in April 2017.
Cornelia is best known for her role as the soap matriarch, in a career spanning over 60 years, but she’s a TV staple Down Under.
As well as breaking through as evil Sister Grace in Young Doctors, Cornelia also appeared in Sons and Daughters and hosts Australia’s version of The Weakest Link.
She is currently being treated in Sydney’s Royal North Shore Hospital where she recently thanked her former producers for spoiling her with a string of strong characters.
“I’d like to thank the producers who hired me because it ain’t easy to put a b***h on television,” she enthused.
Cornelia first shared news of her cancer earlier this year in an interview with The Telegraph.
“I discovered I had bladder cancer,” she explained. “This then spread to my hip bone which fractured, and then I almost died from loss of blood due to an ulcer in my throat.
“Despite all this, I am still here, as the old song goes.”
She continued: “When I got the ulcer in my throat, I did truly believe that this time my luck had finally run out.
“I was a total mess according to my surgeon. He told me he didn’t believe they could get me back from the brink, but somehow they did.”
Home and Away airs on Channel 5.
