Kate Middleton, Prince William escape to vacation home with kids amid her cancer battle

Middleton said that William, 41, has been a huge support throughout her struggles and that they had waited to announce the news until their children fully understood her condition.

However, it wasn’t until after the hospital where Middleton underwent surgery experienced a security breach in which multiple staffers attempted to access her medical files that she revealed her diagnosis.

“They probably felt the pressure to announce,” royal expert Valentine Low told Page Six exclusively last week. “It was too much to bear in the end; they had to say something.”

The princess had been staying out of the spotlight amid her recovery, spurring wild conspiracy theories about her health and whereabouts despite her reps confirming that she would not be returning to her in-person royal duties until after Easter.

Worries heightened when Middleton posted a heavily doctored photo of herself with her kids, Prince George, 10, Princess Charlotte, 8, and Prince Louis, 5, on British Mother’s Day after having been absent from any official events since last December.

Middleton issued an apology over the Photoshopped portrait and quelled concerns when she and William were spotted shopping at a farm stand in Windsor amid the mayhem.

The cancer news comes shortly after King Charles II announced his own battle with the disease on Feb. 5.

Charles, 75, showed his support for his daughter-in-law, with a Buckingham Palace spokesperson telling Page Six that the reigning monarch is “so proud of Catherine for her courage in speaking as she did.”

The British sovereign has “remained in the closet contact with his beloved daughter-in-law” and will continue to offer “love and support,” the spokesperson added.

Middleton and Charles reportedly had a private lunch a day before she announced her diagnosis to discuss their “common health experience.”
