In a heartfelt revelation, John F. Kennedy’s granddaughter has shared that she has been quietly battling terminal cancer for over a year.

On the 62nd anniversary of JFK’s assassination, Tatiana Schlossberg, 35, disclosed her diagnosis of acute myeloid leukemia, a severe form of blood cancer, which she learned about in May 2024.

Schlossberg recounted that prior to the diagnosis, she exhibited no symptoms and considered herself among the healthiest people she knew. The disease was only detected through routine blood tests conducted after the birth of her second child.

In an essay for The New Yorker, titled “A Battle With My Blood,” Schlossberg detailed how her diagnosis unfolded when a doctor observed an unusual imbalance in her white blood cell count.

“A typical white-blood-cell count ranges from four to eleven thousand cells per microliter. Mine was at one hundred and thirty-one thousand cells per microliter,” she wrote.

‘It could just be something related to pregnancy and delivery, the doctor said, or it could be leukemia,’ she recalled being told. 

The sister of Kennedy political scion Jack Schlossberg, the author said she was diagnosed with a ‘rare mutation called Inversion 3’, which ‘could not be cured by a standard course.’ 

Schlossberg said she was bewildered by the news, and said despite being nine-months pregnant she was routinely exercising and ‘didn’t feel sick.’ 

‘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 wrote.

Schlossberg said she spent five weeks at Columbia-Presbyterian Hospital after giving birth, before she was transferred to Memorial Sloan Kettering for a bone-marrow transplant. 

She then underwent grueling chemotherapy at home, and in January she joined a clinical trial of CAR-T-cell therapy, a type of immunotherapy against certain blood cancers. 

In a devastating blow following the news, Schlossberg said she was eventually told by doctors that she had just a year left to live. 

Schlossberg lamented the impact that her diagnosis had on her storied family, which has famously suffered a series of tragedies and scandals over the years. 

‘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,’ she wrote. 

‘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.’ 

Schlossberg’s mother Caroline Kennedy served as the US Ambassador to Australia under President Joe Biden from 2022 to 2024, and previously served as Ambassador to Japan under Barack Obama.

Schlossberg also praised her husband George Moran, a physician, for supporting her through her treatment

Schlossberg also praised her husband George Moran, a physician, for supporting her through her treatment. 

‘George did everything for me that he possibly could. 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 wrote. 

She continued: ‘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. 

‘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.’
