Kate to attend Trooping the Colour in first event since cancer diagnosis

This is the most significant update on Catherine’s health since revealing in March she had cancer, in a statement written in her own words.

It is accompanied by a new photograph of the princess, taken by photographer Matt Porteous, which shows her near her home in Windsor.

But there is caution with the positive message.

“As anyone going through chemotherapy will know, there are good days and bad days,” she says.

“On those bad days you feel weak, tired and you have to give in to your body resting. But on the good days, when you feel stronger, you want to make the most of feeling well,” says the princess.

“I am learning how to be patient, especially with uncertainty. Taking each day as it comes, listening to my body, and allowing myself to take this much needed time to heal.”
