King Charles has shared his "heartfelt thanks" for messages of support from around the world after revealing his shock cancer diagnosis.
It's his first public comment since Buckingham Palace announced he would postpone some engagements to undergo treatment.
"I would like to express my most heartfelt thanks for the many messages of support and good wishes I have received in recent days," he wrote on the royals' website.
"As all those who have been affected by cancer will know, such kind thoughts are the greatest comfort and encouragement.
"It is equally heartening to hear how sharing my own diagnosis has helped promote public understanding and shine a light on the work of all those organisations which support cancer patients and their families across the UK and wider world. My lifelong admiration for their tireless care and dedication is all the greater as a result of my own personal experience."
The King's cancer diagnosis was revealed on Tuesday morning (NZT), with a statement from the Royal Family saying it had been picked up during his recent time in hospital to undergo a corrective procedure for an enlarged prostate. It is not yet known what form of cancer he has but Reuters reported a royal source confirmed it wasn't prostate cancer.
Charles' wife, Queen Camilla, said on Thursday that Charles was doing "extremely well".
With the king undergoing treatment and Prince William's wife Kate recovering from abdominal surgery, the onus is on the remaining royals - especially William and Camilla - to provide the public face of the monarchy.
