“I would like to express my most heartfelt thanks for the many messages of support and good wishes I have received in recent days,” the king said in a statement Saturday. “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 U.K. and wider world. My lifelong admiration for their tireless care and dedication is all the greater as a result of my own personal experience.”
