Robin Gibb is elated that his liver cancer is "almost gone."

The 62-year-old Bee Gees musician is undergoing chemotherapy treatments after being admitted to the hospital with the disease in November.

His health has drastically improved since his initial admission and Robin is looking forward to his future.

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," Robin told host Steve Wright in an interview on BBC Radio 2 today. "I am very active and my sense of well-being is good."

Robin is glad he decided to speak up about the pain he was experiencing, as he has achieved remarkable results.

"I mean the fact is, I've never spoken to anybody about my condition or the condition that I was in and a lot of them go over the top to the point where they're telling me things that I didn't even know about myself," Robin explained. "Well, it's all simple. 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."

Before he sought treatment, Robin believed that the pains in his stomach were related to a condition he suffered from previously. The star has had repeated health problems due to a twisted bowel and his brother Maurice died nine years ago from the malady at the age of 53.

Robin is elated that his innards are now functioning harmoniously.

"I feel better than I did ten years ago. I'm active, my appetite's fantastic, the plumbing is all in perfect working order," Robin said. "If I had a choice about how I'd like to feel for the rest of my life, this would be it. If I wanted to tick all the right boxes about sense of well-being, it would be now. This is the way I'd like to feel. I don't know how I could feel any better."
