NEW YORK CITY, NEW YORK: The Kennedy family is facing another heartbreaking tragedy as Tatiana Schlossberg, the granddaughter of President John F Kennedy, has revealed that she has less than a year to live.

The 35-year-old author and environmental journalist shared the news in a personal essay published in The New Yorker on Saturday, November 22, disclosing her battle with a rare and aggressive form of cancer.

Diagnosis came hours after childbirth

Schlossberg’s diagnosis came during what should have been a joyous moment. She revealed that doctors discovered the cancer just hours after she had given birth to her second child, a daughter, in May 2024.

"Maybe my brain is replaying my life now because I have a terminal diagnosis, and all these memories will be lost," Schlossberg wrote in the gut-wrenching essay.

Doctors noticed her blood counts were abnormally high shortly after delivery. While initially hoping it was pregnancy-related, further testing confirmed that she had acute myeloid leukemia with a rare mutation known as "Inversion 3," a condition typically seen in much older patients.

Tatiana Schlossberg reveals she couldn’t change daughter’s diaper

Since the diagnosis, Schlossberg has undergone grueling treatments, including chemotherapy, a bone-marrow transplant, and blood transfusions.

She described the agony of being separated from her newborn due to her compromised immune system.

"I didn't ever really get to take care of my daughter- I couldn't change her diaper or give her a bath or feed her, all because of the risk of infection after my transplants," she wrote.

In January, she joined a clinical trial for CAR-T-cell therapy, a cutting-edge immunotherapy. However, the prognosis remained grim, with her doctor informing her that she had "around a year to live."

Tatiana Schlossberg fears her children won’t remember her

Tatiana is the daughter of Caroline Kennedy and Edwin Schlossberg, and the sister of Jack and Rose Schlossberg. Her revelation adds a somber new chapter to the Kennedy family history, often marked by public service and private pain.

Despite the terminal prognosis, Schlossberg expressed profound gratitude for her husband, George Moran, and her family, who have been by her side "unflinchingly" throughout the ordeal.

"My first thought was that my kids... wouldn't remember me," she confessed. "My son might have a few memories, but he'll probably start confusing them with pictures he sees or stories he hears."
