Kate Middleton Still Undergoing Cancer Treatment But to Attend Trooping the Colour

Catherine, Princess of Wales, 42, revealed in a written message Friday that she is still receiving cancer treatment but plans to attend the Trooping the Colour event.

The Princess did not disclose the specific type of cancer she has been diagnosed with. However, experts have suggested that the diagnosis is a "familiar scenario" for someone with Catherine's athletic background.

Catherine, a former high school athlete who has continued to participate in sports as a working royal, has been a regular attendee of the Wimbledon tennis championships.
