King Charles III expresses 'heartfelt thanks' for support after cancer diagnosis

King Charles III is thanking the public in his first statement since being diagnosed with cancer.

The British royal family on Saturday released a statement from Charles extending his "most heartfelt thanks for the many messages of support and good wishes" he has received in recent days.

"As all those who have been affected by cancer will know, such kind thoughts are the greatest comfort and encouragement," he said.

On Sunday, Charles attended church services for the first time since his diagnosis. He and Queen Camilla were seen going to St. Mary Magdalene Church in England, and the king offered a wave as he walked out.
