Kate Middleton and Prince Louis took pictures that the Princess of Wales shared before World Cancer Day, and hers had a deeper meaning. All about the symbolism.

"Don't forget to nurture all that which lies beyond the disease," the picture was captioned on Instagram. The Princess of Wales signed the post off with a 'C' which stands for Catherine, her full first name. The post also includes a second photo, featuring a close-up of fern branches with the same powerful message.

Kate, the Princess of Wales, is sharing both a personal message of hope and a personal photo in honor of World Cancer Day. Kate, who announced in January that she is in remission from cancer, shared a photo of herself Monday standing outside in nature with her arms stretched wide.
