Buckingham Palace, the British monarchy, that is still evolving after the 70-year reign of the late Queen Elizabeth II is under utmost pressure as King Charles III has been diagnosed with cancer.

Charles’ task after he succeeded his mother around 17 months back is to demonstrate the 1,000-year-old institution remains relevant in the modern nation. However, the 75-year-old king will have to lead while undergoing his cancer treatment.

On Monday, the palace announced that the king had been diagnosed with an undisclosed form of cancer. Despite that, Charles announced his plans to continue fulfilling his state duties which includes reviewing government papers and meeting with the prime minister. However, he announced that he would be stepping back from public appearances.

Though royal experts say that the diagnosis is unlikely to destabilize the House of Windsor, significant pressure still exists.

Charles, having waited nearly 74 years, longer than any previous heir, to ascend the throne, is now faced with the challenge of leaving his mark on the monarchy within a limited timeframe.

Despite the mostly ceremonial nature of the constitutional monarch’s duties, the demands of the royal role can be taxing. From processions in full regalia to meetings with political leaders and events celebrating British citizens’ achievements, Charles found himself engaged in 161 days of royal commitments during his initial year as king.”

“I don’t think he will go anywhere anytime soon,” said Joe Little, managing editor of Majesty Magazine. “I still think that abdication is not a word that is bandied about at Buckingham Palace. I mean, who knows what the coming years will bring, but with the best will in the world, Charles III will reign as his mother did, and until the moment of his death.”

Charles’ illness comes at an awkward time. Not only he is stepping away from public duties, but his daughter-in-law, Kate, the Princess of Wales won’t resume her royal tasks anytime soon due to her abdominal surgery. As two of the most viable members of the royal family are sick, it will be challenging for the family to keep up.
