A source told the Sunday Timesmagazine: “It wasn’t really about the drama of the last few weeks, though, obviously, that has been upsetting. She felt she had to do it because of who she is. It was more that she knows she is a public figure and has a wider leadership responsibility.
“It was all her, she wrote every word of it - it came together very quickly.”
It was also reportedly Kate’s idea to share the news in a video message rather than a written statement, which would have been more “jarring”.
Following public support for the Princess of Wales, Kensington Palace released a statement, saying: “The Prince and Princess are both enormously touched by the kind messages from people here in the UK, across the Commonwealth and around the world in response to Her Royal Highness’ message.
“They are extremely moved by the public’s warmth and support and are grateful for the understanding of their request for privacy at this time.”
Meanwhile, Kate, 42, and her father-in-law King Charles, 75, who is also battling cancer, have bonded even more over their illnesses and spent time together when they were both being treated in The London Clinic.
A source told the Sun newspaper: “It was held at Windsor Castle and was only between the two royals.

“They would have had lots to discuss and share because just weeks earlier the King had begun his course of treatment and dealt with announcing his diagnosis.
“The King left his lunch feeling very emotional. They are very close and he thinks of Catherine as his daughter.
“There is no doubt there is a lot they can share and can use each other for support during their own deeply personal cancer battles.
“There is a very strong relationship between their majesties and the Waleses. They are very close, even more so at the moment.”
