King Charles, who has been diagnosed with cancer, is slated to undergo "highly specialized" and "less invasive" treatment in London.
The 75-year-old monarch, presently recuperating at Sandringham, will return to London for his treatment, according to reports.
"Cancer treatments have made significant advancements in recent years, becoming more sophisticated and less intrusive compared to earlier methods. This results in improved efficacy and reduced side effects," a source informed The Mirror.
In light of his treatment, Prince William's father has postponed his public duties to minimize the risk of infection or exposure to viruses.
Other working members of the royal family are expected to offer their support during this challenging period.
Meanwhile, Prince William resumed his official duties on Wednesday, presiding over an investiture at Windsor Castle and attending a gala for the London Air Ambulance Charity, where he was joined by Hollywood actor Tom Cruise.
This marks the Prince of Wales's first public engagement since the Princess of Wales underwent abdominal surgery on January 16.
