Princess Kate was diagnosed with cancer in March 2024 and underwent preventative chemotherapy, before announcing she was in remission in January 2025, with royal sources say the tumultuous experience brought the couple closer together11:40, 05 Jul 2026In March 2024, Princess Kate stunned the world with the announcement that she had been diagnosed with cancer and was undergoing preventative chemotherapy. The bombshell health revelation saw the Princess of Wales step back from her royal duties for several months, before she confirmed in January 2025 that she had gone into remission.‌During a visit to the Royal Marsden Hospital last year, Kate spoke openly about her cancer experience for the first time, sharing how she was adapting to a "new normal" while looking forward to a "fulfilling year ahead." Kate certainly delivered on that promise, returning to royal duties with her trademark grace and unwavering commitment to the Firm.‌‌Now firmly on the other side of her gruelling health battle, both the Prince and Princess of Wales have spoken candidly about the toll her cancer journey took on the entire family.A source close to William and Kate previously lifted the lid on how the harrowing ordeal ultimately brought the couple closer together, telling The Times earlier this year how their outlook has fundamentally changed.The Wales' friend told the publication: "On a very human level, if you go through an experience like this, it changes you. And it can change you for the good. At heart, they're both good, proper people. While you'd never wish it upon them, it's made them stronger as a couple and stronger as individuals, with probably more wisdom than they had before.‌"When your kids are young, you just barrel forward at great pace and everything is just about the growth of the family. And with this, you know, it's the obvious cliché, but it sort of stops you in your tracks."During a visit to Colchester Hospital in Essex in July last year, Kate spoke candidly about her cancer treatment, bravely opening up about the "very scary, very daunting experience". She noted there was an expectation that patients "crack on, get back to normal".‌She described her cancer diagnosis as "life changing" and the treatment and recovery a "rollercoaster", speaking openly about the significance of a holistic "mind, body and spirit" approach.She confided to patients at the hospital: "You put on a sort of brave face, stoicism through treatment. Treatment's done, then it's like 'I can crack on, get back to normal' but actually the phase afterwards is really difficult. You're not necessarily under the clinical team any longer but you're not able to function normally at home as you perhaps once used to."And actually someone to help talk you through that, show you and guide you through that sort of phase that comes after treatment I think is really valuable." She went on to add: "You have to find your new normal and that takes time."‌William also opened up about Kate's cancer battle back in October, speaking frankly to Eugene Levy for his programme The Reluctant Traveller, where he confessed to feeling "overwhelmed" by the health struggles affecting his family, and how it had led him to "not great places".Article continues below"You know life is sent to test us as well and it definitely can be challenging at times, and being able to overcome that is what makes us who we are," he said. "You know, I'm so proud of my wife and my father, for how they've handled all of last year. My children have managed brilliantly as well."
