On April 30, the monarch, 75, accompanied by his wife Queen Camilla, 76, visited a cancer hospital in London. During the poignant outing, they spent around an hour meeting with medical specialists and patients to emphasize the importance of early cancer detection and learn more about the support on offer. The visit to the University College Hospital Macmillan Cancer Centre marks King Charles' first official public engagement since his cancer diagnosis was announced on Feb. 5. Following his diagnosis, he has continued working behind the scenes and hosting small audiences. He also greeted well-wishers after attending a church service on Easter Sunday. While the hospital has not been directly involved in the monarch's medical care, highlighting the importance of early detection was one of the reasons King Charles went public with his cancer diagnosis. A spokesperson for Buckingham Palace previously stated that this decision was made "in the hope it may assist public understanding for all those around the world who are affected by cancer."

"For me, it’s nice to see him back and we all missed him. He’s come here today to see people who’ve got cancer and show that he, and they’re not alone.” King Charles and Queen Camilla stopped to wave to the cameras before being greeted by senior hospital staff and dignitaries. Inside, the monarch was welcomed by cheers from ranks of hospital staff gathered in the main central hall.

Royal aides also stressed Tuesday that while his appearance in public shows that people can continue to work with cancer — and return to work when they’re advised as able to do so by doctors — everyone has their own path to follow as they are treated for the condition. King Charles isn't the only member of the royal family undergoing cancer treatment. His daughter-in-law, Kate Middleton, revealed her cancer diagnosis last month after weeks of speculation about her health. In an emotional video announcement, she shared a personal message with those affected by the disease. "At this time, I am also thinking of all those whose lives have been affected by cancer. For everyone facing this disease, in whatever form, please do not lose faith or hope," she said. "You are not alone."  Press Association via AP Images King Charles and Queen Camilla visit University College Hospital in London Related: Has King Charles Finished Cancer Treatment?

Upon arrival, Charles and Camilla met with clinicians and learned about their use of groundbreaking technology, such as CT scanners, which aid in early cancer detection. Charles, the new Patron of Cancer Research UK, took the opportunity to meet the charity’s Chief Clinician, Professor Charlie Swanton. Swanton has spearheaded a collaboration with 250 researchers and clinicians based at 19 centers across the U.K. Their research focuses on understanding the evolution of lung cancer over time and the reasons behind treatment ineffectiveness.
