"Kate Middleton, Britain's Princess of Wales, announced that she is in remission from cancer and expressed her gratitude to The Royal Marsden hospital for her care. She underwent chemotherapy after a cancer diagnosis and major surgery a year ago. Kate's visit to the hospital marked her first solo public engagement since returning to official duties. She also became joint patron of the specialist cancer unit with her husband, Prince William. The couple has faced a challenging year with both of them undergoing cancer treatment."
