Kate Middleton's brother shares rare glimpse into tough cancer battle

James Middleton is opening up about supporting his sister Kate Middleton through her cancer treatment.

James spoke about the challenging time while talking about his new book, which details his struggle with attention deficit disorder and depression.

While speaking to U.K. paper The Times, he said, “What I think is that, as a family, you learn to see and process and understand things. For her and her family, it was a challenging time, and I know for us and our bigger family, it was a challenging time, but I think it’s about communication and it’s about offering support and help where you can."

"Being there for someone is such an important part, and it doesn’t necessarily have to be on your terms, and it shouldn’t be on your terms. It should be on their terms; unconditional: ‘I’m not doing it for something in return. I’m doing it because I love you,’ " he continued.

"And that’s the simplest way of really demonstrating love. You can do it in all these various fancy ways, but actually, you know, it is just generally being there,” he added.

Princess Kate’s cancer diagnosis came as a shock to her family and her fans. In March 2024, she announced the diagnosis and told fans she was undergoing treatment. The Princess of Wales then kept out of the public eye for most of the year and returned to public-facing duties in December with her annual Christmas Carol concert.
