Katherine Schwarzenegger publicly expressed her support for her cousin, Tatiana Schlossberg, following Schlossberg’s disclosure of a terminal cancer diagnosis. Schlossberg, a granddaughter of former President John F. Kennedy, shared details of her battle with acute myeloid leukemia in a recent essay for The New Yorker.
Schwarzenegger, 35, took to Instagram on Sunday, November 23, to share screenshots from the essay. She urged her followers to read the "profound piece," which was published a day earlier.
"I only have tears and rage reading that this is her reality," Schwarzenegger wrote, praising Schlossberg as an "extraordinary" human being. She admired her cousin as a "human, mother, wife, daughter, writer, and fighter."
Schwarzenegger also extended gratitude to the doctors and nurses aiding Schlossberg. She encouraged readers to reflect on how current societal conditions affect those in the medical field and patients like her cousin.
This public display of support followed a similar tribute from Schwarzenegger’s mother, Maria Shriver. Shriver, 70, a niece of JFK, also posted on Instagram.
Shriver called Schlossberg "my cousin Caroline’s exceptional daughter" and a "wonderful writer and journalist, wife, mother, daughter, sister, and friend." She described the essay as an "ode to all the doctors and nurses striving on the front lines of humanity."
Shriver concluded her message by encouraging readers to "be grateful for the life you are living today, right now, this very minute."
Schlossberg, 35, is the daughter of Caroline Kennedy and Edwin Schlossberg. She is also a cousin to Robert F. Kennedy Jr.
She received her cancer diagnosis after giving birth to her second daughter in May 2024. Schlossberg and her husband, George Moran, are also parents to a 3-year-old son.
Doctors have indicated that Schlossberg has approximately one year to live.
In her essay, Schlossberg revealed that a doctor initially detected an imbalance in her white blood cell count. This was first attributed to childbirth complications.
Further medical investigation, however, determined she has "a rare mutation called Inversion 3."
Schlossberg recounted her disbelief upon receiving the diagnosis. She stated, "I had swum a mile in the pool the day before, nine months pregnant. I was not sick. I didn’t feel sick."
She emphasized her previous healthy lifestyle, including routinely running miles in Central Park. Schlossberg added, "I had a son I loved more than anything and a newborn to care for. This could not be my life."
