The Princess of Wales made the shocking announcement in a video message following weeks of speculation about her whereabouts.
Kate, Britain’s Princess of Wales, said on Friday she was undergoing preventative chemotherapy after tests taken after she had major abdominal surgery in January revealed that cancer had been present.
Kate, 42, the wife of heir to the throne Prince William, spent two weeks in hospital in January after undergoing what her office said at the time was successful, planned surgery for an unspecified but non-cancerous condition.
“My medical team therefore advised that I should undergo a course of preventative chemotherapy and I am now in the early stages of that treatment,” Kate said in the video which was filmed on Wednesday.
