The Princess of Wales has disclosed that she has been diagnosed with cancer and is in the early stages of receiving chemotherapy treatment.

Amid questions about her whereabouts, Kate Middleton, the Princess of Wales, has confirmed she has undergone treatment for cancer in a health update Friday.

In an emotional video, Middleton said that while her condition was originally thought to be non-cancerous, cancer was found in her system following abdominal surgery and she is now in the “early stages” of preventative chemotherapy. She did not confirm the type of cancer.

“It has been an incredibly tough couple of months for our entire family, but I’ve had a fantastic medical team who have taken great care of me, for which I am so grateful,” she said in the video, which was reportedly recorded in Windsor on Wednesday.
