Caroline Kennedy's Daughter Tatiana Schlossberg Diagnosed with Terminal Cancer

Tatiana Schlossberg has terminal cancer.

In a new essay published by The New Yorker on Saturday (November 22), the 35-year-old daughter of Caroline Kennedy and Edwin Schlossberg revealed that she has been diagnosed with acute myeloid leukemia and that doctors have told her she has less than a year to live.

“A few hours later, my doctor noticed that my blood count looked strange,” Tatiana wrote. “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.”

“It could just be something related to pregnancy and delivery, the doctor said, or it could be leukemia,” she recalled, adding that she was eventually diagnosed with “a rare mutation called Inversion 3.”

Tatiana went on to share that she “could not be cured by a standard course.” She was initially told she would need months of chemotherapy and a bone-marrow transplant.

“I did not — could not — believe that they were talking about me,” Tatiana wrote. “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.”

“I had a son whom I loved more than anything and a newborn I needed to take care of,” she continued.

Tatiana and husband George Moran, who married in 2017, shared a 3-year-old son and a 1-year-old daughter.

She eventually spent five weeks at Columbia-Presbyterian Hospital after giving birth to her daughter. She was then transferred to Memorial Sloan Kettering for a bone-marrow transplant and underwent chemotherapy at home.

In January, Tatiana joined a clinical trial of CAR-T-cell therapy, which is a type of immunotherapy against certain blood cancers. Eventually, she was told by her doctor that she had a year left to live.

Also in her essay, Tatiana praised her husband for all of his support throughout her battle.

“George did everything for me that he possibly could,” she wrote. “He talked to all the doctors and insurance people that I didn’t want to talk to; he slept on the floor of the hospital.”

She also thanked her parents and her siblings Jack and Rose for their help and support.

“My parents and my brother and sister, too, have been raising my children and sitting in my various hospital rooms almost every day for the last year and a half,” Tatiana continued. “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. This has been a great gift, even though I feel their pain every day.”

She added, “For my whole life, I have tried to be good, to be a good student and a good sister and a good daughter, and to protect my mother and never make her upset or angry. Now I have added a new tragedy to her life, to our family’s life, and there’s nothing I can do to stop it.”

As for her own family, Tatiana wrote, “Mostly, I try to live and be with them now. But being in the present is harder than it sounds, so I let the memories come and go.”

Tatiana‘s sad news comes just weeks after Jack announced he was running for Congress.
