Britain’s King Charles is doing well after having planned treatment to address an enlarged prostate on Friday, a royal source said after he was admitted to the same hospital where his daughter-in-law Kate is recovering from surgery.

The king was accompanied by his wife Queen Camilla to the private London Clinic in west London, where Kate, the Princess of Wales, is also having treatment after undergoing abdominal surgery last week.

A smiling Camilla said Charles was “fine” when she left some hours later, and a royal source confirmed the procedure had taken place and that he was doing well.

“His majesty would like to thank all those who have sent their good wishes over the past week and is delighted to learn that his diagnosis is having a positive impact on public health awareness,” Buckingham Palace said in an earlier statement.

Last week the palace that Charles, 75, would undergo a “corrective procedure” for a benign condition which was common among men over 50. Royal aides have declined to say how long the king would stay in hospital but his upcoming public engagements have been postponed to allow a short period of recuperation.

Britain’s royals usually do not disclose details of illnesses, regarding all medical issues as a private matter, but Charles was keen to share details of his condition to encourage other men experiencing symptoms to have a medical check.
