Kate Middleton has not publicly disclosed the exact type of cancer she was diagnosed with. It was revealed following a major abdominal surgery in January 2024 that was initially believed to be noncancerous, but tests afterward showed cancer was present. Medical experts have speculated possibilities including uterine or ovarian cancer, gastrointestinal cancers such as colorectal cancer, or other abdominal cancers, but no official confirmation of the specific type has been made by the Princess or Kensington Palace. Kate Middleton has since undergone chemotherapy and as of January 2025, announced that her cancer is in remission, and she remains focused on recovery.
