Kate, Britain’s Princess of Wales, and her husband Prince William have been “enormously touched” by the messages of support received since she announced her cancer diagnosis, a Kensington Palace spokesperson said on Saturday.

Kate said on Friday she was undergoing preventative chemotherapy after tests done following her major abdominal surgery in January revealed cancer had been present.

The 42-year-old wife of heir to the throne Prince William, called the cancer discovery a “huge shock”. The news comes as a fresh health blow to the British royal family: King Charles is also undergoing treatment for cancer.

Kate’s statement via a video message, which was filmed at Windsor Castle on Wednesday, triggered an outpouring of support from well-wishers.

“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,” the Kensington Palace spokesperson said in a statement.

“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.”
