Duchess Catherine wrote her entire cancer diagnosis speech herself.
Last week, after months of speculation, Duchess Catherine shared a video message in which she revealed she has been diagnosed with cancer and is currently undergoing chemotherapy treatment.
A source told The Sunday Times magazine: "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."
And, it was also reportedly Catherine'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, Catherine, 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.
They pair also had lunch together in Windsor on the day Catherine made her announcement.
A source told The Sun newspaper: "It was held at Windsor Castle and had 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."
