Queen Camilla gives new update on Kate Middleton post cancer diagnosis

Queen Camilla has given an update on the health of Kate Middleton a week after the Princess of Wales revealed in an emotional message she was to undergo preventative cancer treatment.

Camilla was at a farmers' market in the UK on a solo outing while her husband, King Charles, undergoes cancer treatment himself.

At the event, two young girls had made a sign for the Princess wishing her the best following the news of Kate's illness.

Camilla promised she would pass the message on before telling the crowd: "I know that Catherine is thrilled by all the kind wishes and support."

Kate has been absent from royal duties since January when she underwent planned abdominal surgery at The London Clinic. That absence sparked a myriad of conspiracy theories about her whereabouts.

The mother-of-three is not expected to return to public life until after the two-week UK Easter holidays.

In her video message - believed to have been written by Kate herself - she said was undergoing preventative chemotherapy after tests carried out following the abdominal surgery 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 triggered an outpouring of support, well wishes and love for the Prince and Princess of Wales as well as their children.

"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 in response.

"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."
