Charles III is feeling "very well" during treatment

Britain's Queen Camilla said her husband King Charles, who is being treated for cancer, is doing "very well" as she greeted people during her visit to Northern Ireland, BBC reported.

Charles has been absent from public duties since January as he is being treated for an unspecified form of cancer, leaving Camilla and Crown Prince William to be the public faces of the royal family.

A schoolgirl outside a shop handed Camilla a card addressed to Charles, and the Queen said: "Thank you! He will be delighted."

Camilla and William have been out and about this week, meeting people and doing charity work, keeping the royal family strong as Kate, Princess of Wales, also recovers from a health problem.

Kate is not expected to return to official duties until after Easter, on March 31, after undergoing abdominal surgery in January to treat a non-cancerous condition.

Interest in her health has kept Kate in the headlines. /BGNES
