On March 10, 2024, Catherine, Princess of Wales—then more commonly referred to in headlines as Kate Middleton—shared her first public message since undergoing abdominal surgery. The brief update appeared on the official Instagram account of the Prince and Princess of Wales alongside a family photograph taken by Prince William.
It was a message of thanks, not a speech or a detailed medical statement. At that point, Kensington Palace had not explained the reason for the operation and had said only that Catherine was recovering privately.
What Kate Middleton’s first message said
The post was published on the U.K.’s Mother’s Day. It showed Catherine with Prince George, Princess Charlotte and Prince Louis. The accompanying caption read:
“Thank you for your kind wishes and continued support over the last two months. Wishing everyone a Happy Mother’s Day.”

She signed the message with the initial “C.” The wording acknowledged the public attention surrounding her recovery without providing further information about her condition, treatment or expected return to work.
That distinction matters. The March 10 post was not a public interview, a video address or Catherine’s first disclosure of cancer. Her cancer announcement came separately on March 22, after post-operative tests.
Why the message attracted so much attention
The announcement came after an unusually long period away from public duties. Kensington Palace had announced on January 17 that Catherine had been admitted to The London Clinic for planned abdominal surgery. The palace said the operation had been successful and that she was expected to remain in hospital for 10 to 14 days.

It also said she was unlikely to resume public engagements until after Easter and asked that her medical information remain private. Catherine left the hospital on January 29 and returned home to Windsor to continue her recovery.

Because the palace gave no diagnosis, the family photograph represented the first visible sign of Catherine since the operation. It was therefore widely described as her first public message during recovery, although the post itself contained little medical information.

The later correction to the original interpretation
At the time of the March 10 post, public reporting based on palace information described Catherine’s condition as non-cancerous. That understanding changed two weeks later. In her March 22 video, she explained that the January surgery had initially been thought to involve a non-cancerous condition, but tests conducted afterward found that cancer had been present.
She did not identify the type or stage of cancer. She said she had begun a course of preventative chemotherapy and asked for privacy while she and her family dealt with the news.
The March 10 image also became part of a separate controversy. Major photo agencies later withdrew the photograph after Catherine acknowledged that she had edited it. She apologized for the confusion. That development occurred after the original post and does not change what the message said when it was first published: it was a short expression of thanks during her recovery.

What happened after treatment
In September 2024, Catherine said she had completed chemotherapy but emphasized that returning to full health would take time. In January 2025, she described her cancer as being in remission during a visit to the Royal Marsden Hospital, where she had received treatment.
Those later updates provide the necessary context for the March 10 post. The original message marked Catherine’s first public contact with supporters after surgery, but it was only the beginning of a series of health updates that eventually included her cancer diagnosis, chemotherapy and remission.
Official royal records continued to show Catherine undertaking public duties in 2026, including cancer-related engagements and support for the Royal Marsden Cancer Charity.

- It did not confirm: The reason for her surgery, the nature of her medical condition or a return-to-work date.
