Katherine Schwarzenegger Publicly Supports Cousin Tatiana Schlossberg After Terminal Cancer Diagnosis

Katherine Schwarzenegger expressed her public backing for her cousin Tatiana Schlossberg, following the announcement by the granddaughter of former President John F. Kennedy that she had received a terminal cancer diagnosis.

Schwarzenegger, aged 35, used Instagram on Sunday, November 23, to post multiple screenshots from an essay Schlossberg, also 35, authored for The New Yorker, an article that appeared just a day earlier and chronicled her struggle with acute myeloid leukemia.

“This is a deeply moving work crafted by my remarkable cousin, Tatiana. It has circulated widely and truly merits everyone's attention. I am filled with both tears and indignation upon learning that this is her current situation. She has navigated this ordeal with immense dignity, and I am profoundly impressed by her as a person, a mother, a spouse, a daughter, a writer, and a resilient individual,” Schwarzenegger stated. “I am, and will remain, thankful for every doctor and nurse assisting her, and I urge you to read her account of how the nation's condition, with its budget reductions and instability, affects and deeply concerns medical professionals and patients undergoing care, much like Tatiana has been for the last eighteen months, and continues to be. My thoughts and affection are with her and her loved ones.”

This Instagram message follows a similar public show of support for Schlossberg from Schwarzenegger’s mother, Maria Shriver, who shared her own tribute on the platform.

Tatiana Schlossberg Critiques Cousin RFK Jr. in Her Cancer Revelation

Schlossberg is the offspring of Caroline Kennedy and Edwin Schlossberg, and a relative of Robert F. Kennedy Jr. Her article revealed that her cancer was diagnosed subsequent to the birth of her second child, a daughter, in May 2024. Schlossberg and her spouse, George Moran, are also parents to a 3-year-old boy.

Schlossberg's prognosis indicates a life expectancy of twelve months.

Shriver, who is former President Kennedy's niece, expressed comparable admiration for Schlossberg in her personal tribute. “Should you have time for only one read today, I implore you to engage with this exceptional literary work by my cousin Caroline’s remarkable daughter, Tatiana,” Shriver, 70, penned. “Tatiana is a gifted wordsmith, a reporter, a wife, a mother, a daughter, a sibling, and a confidante. This writing delves into her experiences over the past eighteen months. It serves as a tribute to all medical practitioners and nurses who labor tirelessly at the forefront of human care. It encompasses numerous aspects, but it is best experienced firsthand, allowing oneself to be moved by one woman's life narrative.”

Shriver went on to add, “May it serve as an encouragement to appreciate the existence you inhabit today, in this precise moment, right now.”

Within Schlossberg’s essay, she disclosed that her physician had observed an irregularity in her white blood cell count, initially attributing it to difficulties during childbirth and delivery. Subsequent inquiry established that she actually possesses “a seldom-seen genetic alteration known as Inversion 3.”

She recounted, “I simply could not — would not — accept that they were referring to my situation. Just the day prior, I had completed a one-mile swim, heavily pregnant. I exhibited no illness. I felt perfectly fine. In truth, I considered myself among the most vigorous individuals I knew. My routine included running five to ten miles in Central Park often.”

Schlossberg further stated, “I had a cherished son whom I adored above all else, and a new infant requiring my care. Such circumstances simply could not be unfolding in my life.”
