Nov. 22 (UPI) -- Tatiana Schlossberg, Caroline Kennedy Schlossberg's daughter and the late President John F. Kennedy's granddaughter, has announced she was diagnosed with acute myeloid leukemia, with a rare mutation, in 2024.

"My parents and my brother and sister, too, have been raising my children and sitting in my various hospital rooms almost every day for the last year and a half. They have held my hand unflinchingly while I have suffered, trying not to show their pain and sadness in order to protect me from it," the 35-year-old environmental journalist and mother of two young children wrote in an essay for the New Yorker magazine published Saturday.

"This has been a great gift, even though I feel their pain every day. 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."

She described in detail how she was shocked to be diagnosed when her blood work raised alarms after the birth of her second child last year.

Tatiana, who said she felt healthy and strong at the time, explained all of the treatments she ultimately had to undergo and how the doctor supervising her latest clinical trial cautiously said he might be able to keep her alive for another year at the most.
