It was Feb. 10 when the king took time to address the diagnosis, which he did by briefly sharing a heartfelt message. 

"I would like to express my most heartfelt thanks for the many messages of support and good wishes I have received in recent days," Charles began. 

"As all those who have been affected by cancer will know, such kind thoughts are the greatest comfort and encouragement," he concluded in a statement released by Buckingham Palace. 

Following what's become nearly six weeks of treatment, Queen Camilla says Charles is "doing very well" during her solo visit to Northern Ireland on Thursday.
