Mandy Moore Moved By Tatiana Schlossberg's Poignant Cancer Battle Announcement

Actress Mandy Moore expressed profound sadness following the public disclosure by Tatiana Schlossberg, daughter of Caroline Kennedy, regarding her terminal cancer diagnosis.

“Her narrative and her eloquent expression deeply moved me,” the 41-year-old Moore posted on her Instagram Stories this past Saturday, November 22. “Such poise and openness amidst the profound struggle she and her loved ones face is truly beyond comprehension.”

The 35-year-old Schlossberg shared in a The New Yorker article, “A Battle With My Blood,” released earlier that Saturday, that she had received a diagnosis of acute myeloid leukemia. Prognosis indicates she has approximately one year remaining. (Tatiana is one of three offspring born to John F. Kennedy’s daughter and her spouse, Edwin Schlossberg.)

“The reductions in funding for cancer research are utterly indefensible. I urge everyone to please read this,” Moore stated, encouraging her audience to engage with Tatiana’s account. “My deepest affection and positive sentiments go out to Tatiana, her spouse, and their offspring.”

Within her personal essay, Tatiana disclosed that her terminal cancer diagnosis came shortly after the birth of her second child, a daughter, in 2024.

“My spouse, George [Moran], and I cradled her, gazing at her and marveling at her fresh presence. Just hours subsequently, my physician observed an unusual appearance in my blood count,” Tatiana recounted. “A typical white blood cell count ranges from approximately four to eleven thousand cells per microliter. Mine registered at one hundred and thirty-one thousand cells per microliter.”

Tatiana stated that medical professionals identified an uncommon leukemia mutation within her blood cells.

“A conventional treatment regimen would not suffice for a cure. I would require a minimum of several months of chemotherapy, designed to diminish the quantity of blast cells in my bone marrow,” she clarified in The New Yorker article. “Subsequently, a bone-marrow transplant would be necessary, holding the potential for a cure. Following the transplant, it was likely I would need ongoing chemotherapy treatments to attempt to avert the cancer's recurrence.”

Tatiana subsequently participated in two clinical trials, during which her oncologist informed her that “he might be able to extend her life for perhaps a year.”

“My initial concern was that my children, whose visages are etched into my mind, would not retain memories of me,” she penned concerning her offspring, born in 2022 and 2024. “My son might recall some moments, but he will likely begin to conflate them with images or narratives he encounters. I never truly had the opportunity to nurture my daughter. I was unable to change her diaper, bathe her, or feed her, primarily due to the heightened risk of infection post-transplant. I was absent for nearly half of her inaugural year.”

Throughout Tatiana’s struggle with cancer, she has received unwavering support from her husband, parents, and her two siblings.

“This unwavering support has been a profound blessing, despite the fact that I sense their sorrow daily,” Tatiana stated. “My entire life, I have endeavored to be commendable—a diligent student, a kind sister, a devoted daughter—and to shield my mother from distress or anger. Now, I have inadvertently introduced a fresh misfortune into her existence, into our family's narrative, and I am powerless to prevent it.”
