Kate Middleton Says 'There Are Good Days and Bad Days' in First Health Update Since Cancer Announcement

The Princess of Wales said in a personal letter, "I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days"

Kate Middleton is "making good progress" in her cancer treatment but says in a personal letter, "There are good days and bad days."

In a message released on June 14, the Princess of Wales, 42, shared her first health update since publicly revealing her cancer diagnosis in March.

"I have been blown away by all the kind messages of support and encouragement over the last couple of months," she began. "It really has made the world of difference to William and me and has helped us both through some of the harder times."

"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days," the royal mom of three continued. "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."

"On the days I feel well enough, it is a joy to engage with school life, spend personal time on the things that give me energy and positivity, as well as starting to do a little work from home," Kate added.

The Princess of Wales also confirmed that she was "looking forward" to attending Trooping the Colour, King Charles' birthday parade, on June 15. The outing will mark her first appearance with the royal family since Christmas.

Kate also shared a "hope" to join "a few public engagements over the summer, but equally knowing I am not out of the woods yet."

"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," she said. "Thank you so much for your continued understanding, and to all of you who have so bravely shared your stories with me."

A new photo was also released of Princess Kate, the public's first time seeing her since her cancer announcement video in March. The snap showed the royal outdoors in Windsor, where she lives with Prince William and their three children, standing beneath a tree with her arms folded as she gazes upward. Photographer Matt Porteous got behind the camera for the snap after taking many of the family's pictures over the years.

The Princess of Wales stated her treatment is "ongoing and will be for a few more months."
