Kate Middleton makes major change in how she works as she turns 43

Kate Middleton will use videos to speak directly to the public after discovering powerful impact of her messages during cancer treatment, according to a report in The Telegraph.

Working members of the royal family carry out more than 2,000 official engagements in the UK and overseas, which vary from visits to community initiatives, welcoming visiting Heads of State, meeting guests at official Garden Parties and presenting members of the public with honours. They also make foreign visits to strengthen Britain's diplomatic and economic relations.

The report comes as Kate Middleton celebrates her 43rd birthday after what her husband Prince William calls a difficult year.

The Princess of Wales was admitted to a hospital for a surgery days after her 42nd birthday last year.

 Later it was announced that she was receiving treatment for an unspecified form of cancer.

The future queen has completed her chemotherapy and has made a couple of public appearances since then.

Prince William on Thursday shared a heartfelt message for his wife on Instagram to wish her on her birthday.

Sharing a picture of his wife, the future William wrote, "To the most incredible wife and mother. The strength you’ve shown over the last year has been remarkable. George, Charlotte, Louis and I are so proud of you. Happy Birthday, Catherine. We love you. W."
