Caroline Kennedy’s Daughter Tatiana Schlossberg, 35, Reveals Terminal Cancer Diagnosis

Tatiana Schlossberg, the 35-year-old daughter of Caroline Kennedy and Edwin Schlossberg, has revealed that she is living with terminal acute myeloid leukemia.

In an essay published by The New Yorker on Saturday, Nov. 22, Schlossberg wrote that she learned about the illness shortly after the birth of her second child in May 2024. A routine check soon after delivery showed a striking rise in her white blood cell count.

“A few hours later, my doctor noticed that my blood count looked strange. A normal white-blood-cell count is around four to eleven thousand cells per microliter. Mine was a hundred and thirty-one thousand cells per microliter,” she wrote. At first, she was told the abnormal result might be linked to pregnancy and delivery, but her doctors also warned it could signal leukemia. Tests later confirmed acute myeloid leukemia with a rare mutation known as Inversion 3.

Schlossberg explained that standard treatment would not be enough to cure her. Initially, she was told to brace for months of chemotherapy followed by a bone-marrow transplant. The news felt impossible to accept, she said, especially because she hadn’t felt unwell. “I did not — could not — believe that they were talking about me,” she recalled, thinking back to swimming a mile in a pool just the day before while nine months pregnant.

At the time, Schlossberg was caring for her older child and a newborn. She and her husband, George Moran, who married in 2017, share a son and a daughter.

After giving birth, she spent five weeks at Columbia-Presbyterian Hospital before transferring to Memorial Sloan Kettering for a bone-marrow transplant. She continued chemotherapy at home. In January, she enrolled in a CAR-T cell therapy clinical trial—an immunotherapy approach used for some blood cancers. Eventually, her doctor told her she likely had about a year to live.

Throughout the ordeal, Schlossberg wrote, Moran has been a constant source of support. “George did everything for me that he possibly could,” she said, describing how he managed conversations with doctors and insurance providers and even slept on a hospital floor to stay close.

She also described the unwavering presence of her wider family. Her parents and siblings have helped raise her children and been beside her through long hospital stays. “They have held my hand unflinchingly while I have suffered, trying not to show their pain and sadness in order to protect me from it,” she wrote, calling their care a profound gift even as she feels their grief alongside her own.

Reflecting on her relationship with her mother, Schlossberg admitted she has long tried to be “a good student and a good sister and a good daughter,” always hoping to shield her family from hurt. Now, she wrote, she struggles with the knowledge that her illness brings new sorrow to their lives—something she cannot undo.

As she looks ahead, Schlossberg said her focus is on being with the people she loves for as long as she can. “Mostly, I try to live and be with them now,” she wrote. “But being in the present is harder than it sounds, so I let the memories come and go.”
