A spokesperson on behalf of the family said: "Following a challenging and committed fight against prostate cancer, Bill passed away peacefully at his home in Suffolk surrounded by his family on Wednesday, 31 August."
The presenter was one of the most familiar faces on breakfast TVBBC
"He was resolutely positive and was hugely buoyed by the support he received from friends, colleagues, and messages from people wishing him luck. It was a great comfort to Bill that so many more men are now testing earlier for this disease," they added.
"Bill will be remembered by many as a remarkable broadcaster who brought warmth and humour into people's homes. He was also a devoted Wycombe Wanderers fan and an ever-aspiring beekeeper.
"Bill was a wonderful husband and father to his three children; his family and friends will miss how he always made them laugh, and the generosity and love he shared with those around him."
The likes of Robert Rinder and Dan Walker were among those to pay their respects to Turnbull on social media.
