Catherine, Princess of Wales, has announced that she's undergoing treatment for cancer in a prerecorded video released Friday (March 22).

"In January, I underwent major abdominal surgery in London, and at the time, it was thought that my condition was non-cancerous," Kate, age 42, said in the video. While the initial surgery was successful, "tests after the operation found cancer had been present."
