Princess Kate of Wales expressed gratitude on British Mother's Day post-surgery through an Instagram family photo.

There is public skepticism about the authenticity of the Instagram post, suggesting it may be damage control.

Fans point out anomalies in the photo, such as the missing wedding ring and the backdrop not matching the season.

Kate is anticipated to resume royal responsibilities after Easter, with no official engagements until then.

King Charles underwent treatment for an enlarged prostate and was diagnosed with cancer on the same day as Kate's surgery.

Buckingham Palace will only provide 'significant updates' on Kate's health, emphasizing the privacy of royal medical matters.

Despite health concerns, King Charles continues some head of state duties.

Buckingham Palace commemorated Mother's Day with a tribute to Charles and the late Queen Elizabeth.
