On Tueday, King Charles III resumed his public duties after a 12-week in absence since his cancer diagnosis.
Buckingham Palace shared few details about the king's prognosis and condition since it announced his cancer diagnosis in February.
King Charles and Queen Camilla visited the University College Hospital Macmillan Cancer Centre, in central London and he had several meetings with staff and patients.
The royals were all smiles as they greeted a crowd of well-wishers who had gathered outside.
During his visit, the king told one patient he was felling "alright" and another that he'd be having his own treatment later that day.
The king's openness to share details about his health publicly this year has signalled a significant departure from tradition, in which Britain's royals do not disclose details of illnesses.
