Mandy Moore was emotionally affected after Caroline Kennedy’s daughter Tatiana Schlossberg revealed her terminal cancer battle.
“Her story and her exquisite way with words absolutely shattered me,” Moore, 41, wrote via her Instagram Stories on Saturday, November 22. “To have this grace and vulnerability in the face of what she and her family are battling is impossible to fathom.”
Schlossberg, 35, announced in an essay for The New Yorker titled “A Battle With My Blood,” published earlier on Saturday, that she was diagnosed with acute myeloid leukemia. She has been given one year to live. (Tatiana is one of the three children of John F. Kennedy’s daughter and her husband, Edwin Schlossberg.)
“The cuts to cancer research are beyond unconscionable. Please do yourself a favor and read this,” Moore wrote, hoping her followers read Tatiana’s story. “Sending all the love and good [thoughts] to Tatiana, her husband and their children.”
In her essay, Tatiana revealed that she was diagnosed with terminal cancer after welcoming her second baby, a daughter, in 2024.
“My husband, George [Moran], and I held her and stared at her and admired her newness. A few hours later, my doctor noticed that my blood count looked strange,” Tatiana wrote. “A normal white-blood-cell count is around four to eleven thousand cells per microliter. Mine was a hundred and thirty-one thousand cells per microliter.”
According to Tatiana, her doctors discovered a rare mutation of leukemia in her blood cells.
“I could not be cured by a standard course of treatment. I would need a few months, at least, of chemotherapy, which would aim to reduce the number of blast cells in my bone marrow,” she explained in The New Yorker piece. “Then, I would need a bone-marrow transplant, which could cure me. After the transplant, I would probably need more chemotherapy, on a regular basis, to try to prevent the cancer from returning.”
Tatiana later underwent a pair of clinical trials, where her oncologist told her “he could keep [her] alive for a year, maybe.”
“My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me,” she wrote of her kids, born in 2022 and 2024. “My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears. 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. I was gone for almost half of her first year of life.”
Throughout Tatiana’s cancer battle, she has tirelessly been supported by her husband, parents and her two siblings.
“This has been a great gift, even though I feel their pain every day,” Tatiana wrote. “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. 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.”
