Schlossberg had spoken candidly about how her life changed in the months after learning she had a rare, aggressive blood cancer. She revealed that her diagnosis came in May 2024, shortly after the birth of her second child, and described the physical toll of treatment alongside the emotional weight of parenting while seriously ill.

A Joyful Birth Followed by a Medical Shock

Schlossberg said her illness was discovered within hours of delivering her daughter at Columbia-Presbyterian Hospital in New York. After an initially joyful window with her newborn and husband, George Moran, doctors noticed an alarming change in her bloodwork.

She highlighted how quickly the situation escalated, including a dramatic spike in her white blood cell count that prompted urgent concern and further evaluation. At first, she believed it might be a temporary postpartum complication, even as the medical team raised the possibility of leukemia.

A Rare Diagnosis at a Young Age

Schlossberg was ultimately diagnosed with acute myeloid leukemia (AML) involving a rare mutation known as Inversion 3. She emphasized how disorienting it felt to receive such a diagnosis while otherwise active and healthy, noting that her doctors associated similar blood cancers with older patients.

In her own words, she struggled to accept that the conversation was about her:

“I did not — could not — believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick. I was actually one of the healthiest people I knew.”

She also addressed speculation about possible environmental exposure, explaining she did not spend time at Ground Zero after 9/11, despite being in New York at the time as a child.

Chemotherapy, Transplants, and Relentless Setbacks

After diagnosis, Schlossberg described a long and punishing treatment plan involving multiple rounds of chemotherapy, with the goal of reducing blast cells and preparing her body for more intensive intervention.

“I could not be cured by a standard course of treatment.”

She went on to undergo two bone marrow transplants — first with stem cells donated by her sister, followed later by a second transplant using an unrelated donor. She also participated in clinical trials, including CAR-T cell therapy, as doctors pursued every possible avenue to slow the disease and extend remission.

Through it all, she wrote about the harsh realities of infection risk and isolation — and how those realities reshaped her ability to mother her children in the way she wanted.

A Mother’s Fear: Being Forgotten

One of the most heartbreaking parts of Schlossberg’s account focused on memory — not her own, but her children’s.

“My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me.”

She explained that because of transplant-related risks, she often could not do everyday parenting tasks like feeding, bathing, or diaper changes, and spent long stretches away from home during her daughter’s earliest months.

Career, Purpose, and the Life She Built

Schlossberg was widely known as an environmental journalist and author. Her book Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have earned major recognition, and she wrote for multiple major outlets while also producing her newsletter, “News from a Changing Planet.”

She also described a marriage shaped by devotion under pressure, crediting Moran for navigating hospital logistics, insurance, and day-to-day stability while she focused on treatment — a partnership that, in her telling, made an unbearable situation survivable.

Even as her illness advanced, Schlossberg stressed that she did not want cancer to become her only identity, returning again and again to the work, writing, and family moments that still made her feel like herself.
