Britain's King Charles attended church Sunday in his first public outing since announcing last week he had been diagnosed with cancer and would postpone some engagements to undergo treatment.
The king, wearing a brown overcoat and carrying an umbrella, waved as he arrived with his wife, Camilla, at St Mary Magdalene church in Sandringham in eastern England.
Buckingham Palace announced Monday that Charles, 75, had been diagnosed with an unspecified form of cancer. The king has been on the throne for less than 18 months following the death of his mother Queen Elizabeth.
Charles, who is spending time at his rural Sandringham estate, issued a message on Saturday expressing gratitude to well-wishers following his diagnosis.
While undergoing treatment, Charles has postponed public engagements but is planning to continue with much of his private work as monarch including having his weekly audience with the prime minister and dealing with state papers.
The cancer was discovered when Charles stayed three nights in hospital last month, undergoing a corrective procedure for a benign enlarged prostate. Beyond confirming it was not prostate cancer, the palace has not given any further details.
