This week, while visiting London's National Portrait Gallery, the Princess of Wales sent a clear message with her toned-down look: She's back to work.

Kate Middleton shared a new picture of herself taken by son Prince Louis to commemorate World Cancer Day weeks after announcing she is in remission from cancer.

World Cancer Day takes place every year today, on. It’s a day filled with hope, honor and recognition for everything people fighting the disease have gone through. This year, Princess Kate Middleton marked the day by sharing an update on her cancer journey.
