'The voice of formula one', who hung up his microphone more than a decade ago, told his former employer, the BBC, that the lymphatic cancer was detected when he was hospitalized last month for a broken pelvis following a fall.
"They've caught it incredibly early. It's treatable, the doctors say my condition is mild and I'm very hopeful," the 89-year-old Briton said.
Meanwhile, Red Bull team boss Christian Horner has admitted he is "honored" but "shocked" to have been selected for an OBE – order of the British empire – in the Queen's birthday honors list.
"It's all a bit unexpected, incredible really," the 39-year-old is quoted by the Express newspaper.
Briton Horner has led the Milton-Keynes based team, owned by the Austrian energy drink, to three consecutive seasons of drivers' and constructors' world championship clean sweeps.
06/17/13 Former Formula One commentator Murray Walker has been diagnosed with cancer. The 89 year old told the BBC that he had been diagnosed with a form of lymphatic system cancer, but said that the condition was treatable.

Walker, who was diagnosed with the illness during tests after breaking his pelvis in a fall last month, will undergo chemotherapy over the next few months.
