Journalist and presenter Dame Esther Rantzen has revealed she has been diagnosed with lung cancer.

The 82-year-old broadcaster and long-time activist and founder of charities Childline and The Silver Line confirmed the news on Sunday, January 29.

In a statement shared to PA news agency, Dame Esther said: “In the last few weeks I have discovered that I am suffering from lung cancer which has now spread.

“At the moment I am undergoing various tests, to assess the best treatment.

“I have decided not to keep this secret any more because I find it difficult to skulk around various hospitals wearing an unconvincing disguise, and because I would rather you heard the facts from me.”

Known as a trailblazer for female broadcasters, Dame Esther became a household name during her career at the BBC.
