Kate Middleton, Prince William's relationship has transformed since her cancer diagnosis

Kate Middleton’s return to the public eye has been a joy for royal fans, following her cancer diagnosis and treatment. 

Now that the Princess of Wales is attending public engagements once again, experts are taking note of the subtle yet powerful ways she has changed—especially in her interactions with Prince William.

Body language expert Judi James analyzed the couple’s appearance at the Commonwealth Day service in London and shared her observations with The Mirror.

"Since Kate's illness, they have been extra tactile and totally connected during their public appearances, using every opportunity to use touches, glances or mimed hugs to move together, coupled up like ice skaters or ballroom dancers," James noted.

She added that Kate and William have shifted from “unison” behaviours to mirrored, free movement behaviours—a change that highlights their deep connection and mutual understanding.

"Here, they performed the equivalent of 'free' movement, putting in their professional appearance in a more traditionally regal way but moving while apart in synchronized, mirrored unity," James explained.

According to James, their body language at the event signaled that they are both in a strong and positive place.

"They walked in together but slightly apart with signs of renewed energy and positivity. William's beaming smile projected ongoing pride in his wife, but he avoided all the steering pats and touches that can imply she has some need of support and encouragement," she shared.

She also noted a sweet moment between the couple, highlighting the strength of their bond.

"When they did connect, sitting together, William's body-scrunched pose and his very youthful smile—with eye crinkling and a peek of the front teeth through his lips in response to Kate's lean and playful smile—suggests a bit of a bashful crush is still going on in their relationship," James observed.

What is Kate Middleton's diagnosis?

Princess Kate shared her cancer diagnosis in March of last year. In a video message she explained that in January last year, she underwent major abdominal surgery in London and at that time, it was thought that her condition was non-cancerous.

“The surgery was successful. However, tests after the operation found cancer had been present. My medical team therefore advised that I should undergo a course of preventive chemotherapy and I am now in the early stages of that treatment,” she shared.

However, she has now completed treatment and is now in remission.
