"During the latest clinical trial, my doctor told me that he could keep me alive for a year, maybe," Schlossberg, a climate change and environmental journalist and the author of "Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have," wrote in an essay in the New Yorker.

"The diagnosis was acute myeloid leukemia, with a rare mutation called Inversion 3. It was mostly seen in older patients," Schlossberg wrote.

"Every doctor I saw asked me if I had spent a lot of time at Ground Zero, given how common blood cancers are among first responders," she wrote. "I was in New York on 9/11, in the sixth grade, but I didn’t visit the site until years later. I am not elderly — I had just turned thirty-four."
