While early research focused on cardiopulmonary function—Prezant’s speciality and an area of great concern in the context of World Trade Center first response—the two studies published in JAMA are rather different. The first, led by Prezant, provides an estimate of future cancer burden among this population. The second, led by Verma, looks at this firefighting population’s rates of the blood cancer multiple myeloma specifically.

In the first study, researchers isolated a group of white male firefighters with a mean age around 50 who were at the World Trade Center site in the days and months after 9/11. They then compared their projected risk of cancer compared to average New Yorkers of the same race, gender, and age. The researchers report that among World Trade Center-exposed firefighters, one...
