King Charles III celebrated his 77th birthday in November 2025, and while he remains publicly active, concerns about his ongoing cancer treatment have increased discussions about succession and evolving royal roles.
During his recent appearances, King Charles offered updates about his health, describing it as a “managed condition” and stating that he feels “not too bad” despite occasional setbacks and brief hospitalizations earlier in the year. Both Palace sources and public comments emphasize he intends to remain engaged with public duties, but treatment is ongoing and might affect his schedule.
There is no official confirmation in credible news sources that a birthday video or statement directly declared Catherine, Princess of Wales, is taking on a greater monarchy role due to Charles’s health.
However, it is widely recognized that both Princess Catherine and Prince William have already increased their participation in senior royal events over the past year. With Charles managing his health and Queen Camilla supporting him,
Catherine’s visibility and involvement—particularly alongside William—have grown as she takes on more significant public duties. These adjustments follow tradition, where senior royals share more responsibilities when the monarch faces health challenges.
