Singer-songwriter Barry Manilow has revealed he will undergo surgery to remove a cancerous spot on his lung.

Manilow, one of the biggest stars of the 70s and 80s, said it was "pure luck" that doctors found the spot early when he had an MRI following weeks of bronchitis.

The 82-year-old, known for a string of hits including Copacabana, Could It Be Magic and Mandy, said doctors do not believe it has spread and he will not need chemotherapy or radiation.

In a statement on Instagram, he said: "As many of you know I recently went through six weeks of bronchitis followed by a relapse of another five weeks.

"Even though I was over the bronchitis and back on stage at the Westgate Las Vegas, my wonderful doctor ordered an MRI just to make sure that everything was OK.
