Kate Middleton makes first public appearance since cancer diagnosis at Trooping the Colour

The Princess of Wales began chemotherapy after doctors detected evidence of cancer during her abdominal surgery.

Kate Middleton has made her royal return amid her cancer battle. 

The 42-year-old Princess of Wales joined her husband, Prince William, and their three children — Prince George, Princess Charlotte, and Prince Louis — at Trooping the Colour, a ceremonial parade in honor of King Charles' birthday, held on Saturday. The event not only marked her first public outing in six months, but also her first since revealing her cancer diagnosis in March.

Middleton, who has attended Trooping the Colour every year (except for during the COVID-19 pandemic), took part in the festivities by riding in a horse-drawn coach with her kids throughout London. She later appeared on the balcony of Buckingham Palace alongside William, their children, Queen Camilla, and King Charles III, who is also battling cancer, and several other members of the royal family.

A video of Middleton and her children getting into their carriage was also posted on her and her husband's joint Instagram account with the caption: "All set for The King’s Birthday Parade!"

The Princess of Wales confirmed that she would be attending Trooping the Colour and provided an update on her health in an Instagram post on Friday. She began chemotherapy after doctors uncovered evidence of cancer during her abdominal surgery. 

"I am making good progress, but as anyone going through chemotherapy will know, there are good days and bad days," she wrote. "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."

While the Princess noted that her "treatment is ongoing and will be for a few more months," she expressed her desire to return to her royal duties in the future.

"I'm looking forward to attending The King’s Birthday Parade this weekend with my family and hope to join a few public engagements over the summer, but equally knowing I am not out of the woods yet," she wrote. "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."

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