Kate Middleton, the Princess of Wales, has not publicly revealed the specific type of cancer she was diagnosed with. The cancer was discovered after she underwent a significant abdominal surgery in January 2024, initially thought to be noncancerous. After surgery, tests found evidence of cancer, and she began a course of preventive chemotherapy. Experts speculate the cancer might be uterine or ovarian, but no official confirmation has been made. Kate announced she is now in remission as of 2024 and has shared her focus on recovery and staying cancer-free.
