How Prince William Has Been Supporting Kate Middleton Throughout Her Health Battle

With Kate Middleton still undergoing treatment for cancer, Prince William has been the face of their family in public and his wife’s No. 1 champion at home.

In 2011, Prince William and Kate Middleton vowed at the altar to look after each other—for better, for worse, for richer, for poorer, in sickness and in health.

Thirteen years later, Kate has needed her husband to be there for her more than ever, the Princess of Wales having shared in March—following months of speculation about the true state of her health—that she was undergoing preventative chemotherapy after a cancer diagnosis.

And in a bizarre twist of fate for the systematically stoic royal family, King Charles III has also been battling an unspecified type of cancer, which until he returned to public-facing engagements in April left William as the highest-ranking public face of the entire operation.
