Read Catherine’s full statement.

I wanted to take this opportunity to personally thank you for all the wonderful messages of support and for your understanding while I was recovering from surgery.

It’s been an incredibly tough few months for our whole family, but I’ve had a fantastic medical team who have taken great care of me, for which I am so grateful.

In January I underwent major abdominal surgery in London and at the time my condition was believed to be benign. The operation was successful. However, tests after the surgery revealed that cancer was present. My medical team therefore recommended that I undergo a course of preventative chemotherapy and I am now in the early stages of that treatment.

This obviously came as a huge shock, and William and I have done everything we can to process and manage this privately for the sake of our young family.

As you can imagine, this has taken time. It took me time to recover from major surgery before I could start my treatment. But most importantly, it has taken us time to explain everything to George, Charlotte and Louis in a way that suits them, and to reassure them that I will be fine.

As I told them; I am doing well and getting stronger every day by focusing on the things that will help me heal; in my mind, body and spirit.

Having William by my side is also a great source of comfort and reassurance. As does the love, support and kindness shown by so many of you. It means so much to both of us.

We hope you understand that we as a family now need some time, space and privacy while I complete my treatment. My work has always brought me a deep sense of joy and I look forward to being back when I am able, but for now I must focus on making a full recovery.

At this time I also think of all those whose lives have been touched by cancer. To anyone facing this disease in any form, please do not lose faith and hope. You are not alone.
