Bee Gee Robin Gibb, who has been increasingly frail in recent months, has been diagnosed as suffering from liver cancer. The 61-year-old learned he had the disease several months ago, but the news only emerged this week when he was rushed to hospital. He is reported to have spent five hours in hospital in Oxford on Tuesday before being allowed home, and his brother and bandmate Barry is reported to have flown to see him - along with his 91-year-old mother Barbara. A source told The Mirror: "Robin is not good and there is a lot of concern for him. You can use your wealth to call in the best experts but sometimes no amount of fame, prestige and money can change things when it comes to cancer. "But Robin is a strong character, he is a fighter and has been encouraged by all the online messages from his fans. Dwina is doing everything possible and hasn’t left his side. "There will be difficult times ahead but Robin will never give up and his loving family will make sure he has everything he needs. There is frustration because Robin has always looked after himself. He doesn’t drink, eats well and exercises daily."
