Tatiana Schlossberg, President John F. Kennedy's granddaughter and Caroline Kennedy's daughter, has died at 35, shortly after revealing a terminal cancer diagnosis of acute myeloid leukemia.

In a heart-wrenching essay for the New Yorker published Nov. 22, Schlossberg said she learned she had acute myeloid leukemia after giving birth to her second child in May 2024. The news came after her doctor noticed an imbalance in her white blood cell count. At the time, doctors estimated she may have less than a year to live.

Her death was confirmed Dec. 30 by The John F. Kennedy Library Foundation, the non-profit organization that provides financial support, staffing and creative resources for the former president's library.

Here's what to know about acute myeloid leukemia and how it's treated.

Acute myeloid leukemia, also called AML, is a rare cancer of the blood and bone marrow.
