Tatiana Schlossberg Dies at 35 After Terminal Cancer Battle
Tatiana Schlossberg — the 35-year-old daughter of Caroline Kennedy and Edwin Schlossberg, and granddaughter of President John F. Kennedy — has died following a public battle with terminal cancer. News reports confirm she passed away at age 35 after previously sharing details of her diagnosis and treatment journey.
ABCSchlossberg had spoken candidly about how her life changed in the months after learning she had a rare, aggressive blood cancer. She revealed that her diagnosis came in May 2024, shortly after the birth of her second child, and described the physical toll of treatment alongside the emotional weight of parenting while seriously ill.Schlossberg said her illness was discovered within hours of delivering her daughter at Columbia-Presbyterian Hospital in New York. After an initially joyful window with her newborn and husband, George Moran, doctors noticed an alarming change in her bloodwork.
She highlighted how quickly the situation escalated, including a dramatic spike in her white blood cell count that prompted urgent concern and further evaluation. At first, she believed it might be a temporary postpartum complication, even as the medical team raised the possibility of leukemia.
A Rare Diagnosis at a Young AgeSchlossberg was ultimately diagnosed with acute myeloid leukemia (AML) involving a rare mutation known as Inversion 3. She emphasized how disorienting it felt to receive such a diagnosis while otherwise active and healthy, noting that her doctors associated similar blood cancers with older patients.In her own words, she struggled to accept that the conversation was about her:
“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.”
She also addressed speculation about possible environmental exposure, explaining she did not spend time at Ground Zero after 9/11, despite being in New York at the time as a child.
