John F. Kennedy’s granddaughter has disclosed that she has terminal cancer and may live for only about another year. Tatiana Schlossberg is the daughter of Kennedy’s daughter, Caroline Kennedy, and Edwin Schlossberg. She shared her diagnosis in an essay published Saturday in “The New Yorker.” Its publication comes on the 62nd anniversary of her grandfather's assassination. Schlossberg says she was diagnosed in May 2024 after the birth of her second child when the doctor noticed her white blood cell count was high. It turned out to be acute myeloid leukemia with a rare mutation.
