Tatiana Schlossberg just revealed that she has received a terminal health diagnosis. 

Fox News reports that Schlossberg did so in an essay that was recently published in The New Yorker.

Schlossberg is the 35-year-old granddaughter of former President John F. Kennedy. She is the daughter of Caroline Kennedy and Edwin Schlossberg, and the second cousin of Robert F. Kennedy, Jr., the current Health and Human Services (HHS) secretary.

Caroline Kennedy's daughter Tatiana Schlossberg, 35, revealed her terminal cancer diagnosis in a New Yorker essay published Nov. 22.

The details

Schlossberg revealed that she has been diagnosed with acute myeloid leukemia with a rare mutation.

The Daily Caller reports:

Tatiana Schlossberg, 35, disclosed her terminal diagnosis in a Saturday essay in The New Yorker, writing that acute myeloid leukemia with a rare mutation has resisted multiple treatments since May 2024. Doctors found the cancer on May 25 when blood tests showed her white cell count had spiked to 131,000 cells per microlitre, more than 10 times normal levels.

Adding further tragedy to the situation is that the diagnosis came, according to the outlet, "just hours after Schlossberg delivered her daughter at Columbia-Presbyterian Hospital in New York."

Schlossberg, in the essay, revealed her first thoughts, after the diagnosis, which were about her kids.

She wrote:

My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me. My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears.

"An embarrassment"

Despite all of this, Schlossberg decided take time to attack her cousin, Robert F. Kennedy, Jr.

The Daily Mail reports:

Tatiana Schlossberg, 35, said she watched in horror from her hospital bed as RFK Jr was confirmed for the top health post in February. She said the health-care system she relied on suddenly felt 'strained, shaky' after RFK Jr's confirmation and that she worried about losing access to leukemia and bone-marrow trials at Memorial Sloan Kettering, her best chance at remission.

She didn't stop there.

The Daily Mail adds:

In the same piece, she launched a scathing attack on her second cousin, RFK Jr, over his appointment as Secretary of Health and Human Services. Schlossberg wrote that RFK Jr was 'mostly an embarrassment to me and the rest of my immediate family' as she underwent CAR-T therapy, a treatment developed through decades of government-funded research.

RFK Jr. has been seeing a lot of this from his family ever since he teamed up with President Donald Trump.
