Kate Middleton, the Princess of Wales, was diagnosed with cancer in early 2024 following a major abdominal surgery in January 2024. Initially, the surgery was thought to be for a non-cancerous condition, but post-operative tests revealed cancer had been present. She then underwent a course of preventative chemotherapy starting in March 2024
. Throughout 2024, Kate took several months off from public duties to focus on her treatment and recovery. She made her first public appearance post- diagnosis in June 2024 at the Trooping the Colour event but noted she was "not out of the woods yet" and would not resume full-time royal duties until fully healthy
. By September 2024, Kate announced she had completed chemotherapy and was in remission, focusing on staying cancer-free and gradually returning to work. She described chemotherapy as "really tough" but expressed relief and determination to adjust to a "new normal"
. In January 2025, Kate officially announced her remission from cancer and visited the Royal Marsden NHS Foundation Trust, where she received treatment, thanking the staff for their care. She continues to resume public engagements while adapting to life after treatment
. The specific type of cancer has not been publicly disclosed by Buckingham Palace or Kate Middleton herself, though it was detected following abdominal surgery
. In summary, Kate Middleton was diagnosed with cancer in early 2024, underwent chemotherapy, and as of early 2025, she is in remission and gradually returning to her royal duties.
