Just moments after Buckingham Palace announced King Charles III has been diagnosed with cancer, questions surfaced over the future of the British monarchy.
Charles' diagnosis came after a prostate procedure he underwent last month, the palace announced Monday, though it did not say what form of cancer the 75-year-old monarch was diagnosed with or the stage.
The diagnosis is not related to the benign prostate condition, officials said.
The palace said Charles began treatment Monday and will postpone public-facing duties for the time being.

"The King is grateful to his medical team for their swift intervention, which was made possible thanks to his recent hospital procedure," Buckingham Palace said. "He remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible."
Still, that didn't stop many from asking "what's next?"
Charles became king after his mother, Queen Elizabeth, died in 2022.
