Queen Camilla of Britain confirmed during her visit to Northern Ireland on Thursday that her husband, King Charles, who is undergoing treatment for cancer, is improving "very well." Charles has been absent from his public duties since January while receiving treatment for an unspecified type of cancer, which has led Camilla and British heir apparent Prince William to represent the royal family publicly. Camilla (76 years old) told a student who gave her a card wishing her husband well, "Thank you. He will be happy."
