Prince William undergoes secret cancer test: Buckingham Palace fears another case like that of Kate and Charles III

Prince William is set to undergo a series of medical tests following the recent passing of his former military flight instructor, Flight Sergeant Zach Stubbings, at the age of 47. Stubbings, who trained the prince during his service at RAF Valley between 2010 and 2013, died after a decade-long battle with multiple myeloma-a cancer affecting the blood and bone marrow.

His death has raised concerns about the health risks associated with prolonged exposure to toxic exhaust fumes from military helicopters, including the Sea King aircraft that William piloted during his service.
