• John F. Kennedy’s granddaughter Tatiana Schlossberg diagnosed with acute myeloid leukemia
• The disease is in an advanced stage

Tatiana Schlossberg, daughter of Caroline Kennedy and granddaughter of former US President John F. Kennedy, has revealed she is suffering from cancer in an advanced stage.

Schlossberg, 35, was diagnosed with acute myeloid leukemia with a rare mutation known as Inversion 3.

She explained that she received the diagnosis on May 25, 2024, the same day she gave birth to her second child, when her doctor noticed an abnormally high white blood cell count hours after delivery and moved her for further testing.

Schlossberg said she initially dismissed the possibility of cancer and was stunned when the diagnosis was confirmed, noting that she considered herself “one of the healthiest people” she knew.

“This could not possibly be my life,” she wrote.

Acute myeloid leukemia begins in the bone marrow and quickly spreads into the blood, according to the American Cancer Society, with common symptoms including weight loss, fatigue, fever, night sweats, and loss of appetite.

The Inversion 3 mutation that Schlossberg carries is listed as an unfavorable AML abnormality.

Schlossberg spent five weeks at Columbia Presbyterian Hospital after giving birth before her blast-cell count dropped enough to begin chemotherapy at home. She later moved to Memorial Sloan Kettering Hospital for a bone marrow transplant, spending over 50 days there before returning home to continue treatment.

In January, Schlossberg joined a clinical trial for CAR T-cell therapy, noting that much of the treatment took place while she was hospitalized, coinciding with her cousin Robert F. Kennedy Jr.’s nomination and confirmation as Secretary of Health and Human Services, a position she said he was unqualified for.

Schlossberg thanked her husband and family for their unwavering support and for spending countless days by her side during treatment.
