Prince William is also reported to be proud of the Princess's bravery in sharing such distressing news with the public and her resilience since undergoing abdominal surgery in January.
The couple expressed their gratitude for the overwhelming support received globally after the Princess's emotional video message was released, with even the Duke and Duchess of Sussex setting aside familial differences to offer their personal support.
In the video filmed at Windsor gardens, the Princess disclosed the discovery of cancer post her successful abdominal surgery, putting an end to weeks of speculation regarding her health.
A royal insider shared, "William is deeply proud of his wife for her courage and fortitude, not just recently, but since her surgery earlier this year.
He is dedicated to safeguarding his family's privacy, especially during this challenging time.
" The Princess, driven by a sense of duty, chose to share her condition with the public in the hope of aiding others and opted for a personal video statement to ensure a more compassionate connection.
The statement penned by the Princess received accolades from leading cancer charities for highlighting the impact on her young family, thereby raising awareness about the concerns of cancer patients.
Kensington Palace expressed gratitude for the outpouring of warmth and support from well-wishers globally and emphasized the couple's need for privacy during this period.
Medical experts have noted a concerning rise in abdominal cancers among younger individuals, reflecting a broader trend that has puzzled scientists.
The Princess, who maintains confidentiality about her specific medical details, released the statement strategically after the school term's end, seeking solace at their Norfolk residence with their children during the Easter break.
Upon the conclusion of the holiday, Prince William will resume public duties while supporting his family, and the Princess will gradually resume official engagements under medical guidance.
Though she may attend events at her discretion, a return to a regular public schedule is not imminent, as her ongoing recovery remains the primary focus for the royal couple.
