Late president John F. Kennedy's granddaughter Tatiana Schlossberg has gone public with her health battle. Tatiana wrote an essay for The New Yorker in November 2025, revealing that she had been diagnosed with acute myeloid leukemia. Doctors estimated that she had one year to live. "I did not - could not - believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn't sick. I didn't feel sick. I was actually one of the healthiest people I knew," Tatiana wrote.
