BBC Radio 5 Live presenter Richard Bacon is to have a throat operation to treat a growth on his vocal cord.

"I'll be off work for four weeks and for the first two weeks I won't be able to speak - not a word," he said. "It couldn't sound more deathly boring."
The 33-year-old told listeners on Monday a specialist had diagnosed a polyp, a non-cancerous growth, by putting a camera down his throat.
The host, whose voice sounds weaker on air, has been given steroids to help.
"I went to the ENT [ear, nose and throat] guy and he shoved a camera down my throat," the former Blue Peter presenter said.
"I expected it to be the size of a pencil or something, actually it wasn't. It was about an inch wide.
"He dropped it down and I rejected it a few times in the way that you do when you put your fingers at the back of your throat. It really was quite an unpleasant process."
The doctor recorded the camera's findings and Bacon, who hosts the 2200-0100 slot from Mondays to Thursdays, has posted a picture of his vocal cords on his page on the 5 Live website.
"Apparently they [polyps] are quite common. Mine is quite an acute one, hence why I think I have to have this operation," he said.
A BBC spokeswoman said it was a personal matter and Bacon's agent was unavailable to comment.
