Royal watchers have followed King Charles III’s health battle after he was diagnosed with an undisclosed type of cancer in February 2024.
“During The King’s recent hospital procedure for benign prostate enlargement, a separate issue of concern was noted,” a statement from Buckingham Palace read at the time. “Subsequent diagnostic tests have identified a form of cancer.”
Details about Charles’ treatments have been kept relatively quiet, with rare health updates from the palace coming in the months following his diagnosis. (Charles’ daughter-in-law Princess Kate Middleton was undergoing treatment for her own cancer battle at the same time.)
After a turbulent year for the royal family, it was confirmed in December 2024 that Charles would be continuing his cancer treatments. In March 2025, it was announced that the king was briefly hospitalized but was recovering at home.
