Photos: King Charles III diagnosed with cancer!

King Charles III has been diagnosed with cancer and has started treatment in London.

The shock diagnosis comes a week after the 75-year-old British monarch left hospital following a separate procedure for an enlarged prostate. King Charles was seen for the first time since leaving hospital on Sunday. 

With Queen Camilla by his side, he appeared to be in good spirits, waving to the public as the pair made their way to St. Mary Magdalene Church in Sandringham, Norfolk, for a Sunday morning church service. 

He has now returned to London and begun outpatient treatment. 

On the advice of his doctors, the King is postponing his public-facing engagements as he receives treatment but will continue with state business

and official paperwork, the palace said. 

He “remains wholly positive about his treatment and looks forward to returning to full public duty as soon as possible,” it added. 

Prince William will be returning to public duties on Wednesday for the first time since his wife, Catherine, had surgery last month. 

It is unclear what her surgery was for, but a royal source told CNN on January 17 that the 42-year-old’s condition was non-cancerous.

Get well soon pops! Cancer sucks!!
