Robin Gibb has flown in a team of alternative medics
The Bee Gees star has undergone seven rounds of chemotherapy in his bid to beat the disease and he is now receiving 24-hour care from naturopath nutritionists - which are thought to be the idea of his wife Dwina - at his home in Thame, Oxfordshire.
As well as the naturopathic approach - which relies on the body`s ability to heal itself through good nutrition, rather than relying on surgery and drugs - Dwina has encouraged the singer to have 20-minute detox sessions.
A close family friend told The Sun newspaper: "Robin is fighting this with dignity and courage. He`s trying everything possible to beat this disease."
In November 2011, Robin - who is a teetotal vegan - revealed details on his battle with liver cancer, which was diagnosed in April.
At the time, he said: "I have been very unwell and am now on the road to recovery, and your prayers and wishes are a great tonic to me. I believe because of you I will get well and my deepest love goes out to you all."
The diagnosis came as a massive blow to Robin after he thought "everything had gone back to normal" following his successful treatment for an intestinal blockage in 2010.
Speaking of the ordeal, he explained: "All this time I`d thought it was wind cramps. But the surgeon said that was typical of the way it manifests. The blockage was so bad that he was surprised it hadn`t burst the day before, but it was too dangerous to delay any longer.
"The relief was enormous, and afterwards I needed no painkillers. Not even an aspirin. I have a vegetarian diet, and a great appetite. Everything seemed to go back to normal."
