The 62-year-old singer insists he is close to being fully recovered after undergoing months of intensive chemotherapy to beat the disease.
He tells BBC Radio 2 host Steve Wright: "The prognosis is that it's almost gone and I feel fantastic and really from now on it's just what they could describe as a 'mopping-up' operation. I am very active and my sense of well-being is good."
Gibb admits even the doctors treating him were surprised by his speedy progress, adding: "I was diagnosed with a growth in my colon. It was removed. And I've been treated for that by a brilliant doctor, and in their own words: 'The results have been spectacular.'
"And they said: 'What are you doing that we don't know about?', and I said: 'I'm not doing anything and in fact I haven't taken a single tablet'.
"I feel better than I did 10 years ago. I'm active, my appetite's fantastic, the plumbing is all in perfect working order."
