King Charles has begun treatment for a form of cancer.

Buckingham Palace says during his recent procedure for benign prostate enlargement, a separate issue was found and subsequent testing identified the cancer.

UK correspondent Gavin Grey says with Prince Andrew not doing anything, Prince Harry gone, and the Princess of Wales also just out of hospital herself -- it puts pressure on the remaining working royals.
