Kate Middleton has not publicly disclosed the specific type of cancer she was diagnosed with. It was revealed that she was diagnosed with cancer following major abdominal surgery in January 2024, initially thought to be for a non- cancerous condition. After tests, cancer was found, and she underwent preventative chemotherapy. Speculation exists that the cancer might be related to female reproductive organs such as uterine or ovarian cancer, but this has not been confirmed by her or Kensington Palace. The decision to keep the type of cancer private aligns with a desire for medical privacy. As of recent updates, Kate Middleton is in remission and has focused on recovery with support from her family.
