Kate Middleton, the Princess of Wales, announced in March 2024 that she had been diagnosed with cancer following an abdominal surgery in January 2024. Initially, the surgery was believed to be for a noncancerous condition, but subsequent tests revealed the presence of cancer. She began preventive chemotherapy shortly after the diagnosis. By January 2025, Kate officially announced she was in remission, meaning the cancer was under control but not necessarily fully cured, as remission indicates a reduction or disappearance of cancer symptoms that requires ongoing monitoring. She has spoken openly about the challenges of recovery, describing it as a difficult and slow process post-treatment. As of October 2025, she has returned to royal duties and remains focused on her health and recovery, supported by her husband Prince William and their children.

Regarding the word "lequel," it is French and translates to "which one" in English, used primarily as a relative pronoun or interrogative word depending on context. In summary, Kate Middleton faced a cancer diagnosis revealed after abdominal surgery, underwent preventive chemotherapy, and as of recent updates, she is in remission and resuming public life while managing ongoing recovery.
