Immune System Cancer Found in Young 9/11 Responders

Researchers say a small number of young law enforcement officers who participated in the World Trade Center rescue and cleanup operation have developed an immune system cancer.

The researchers looked at about 28,000 emergency responders who spent time amid ground zero dust, and found eight cases of multiple myeloma.

Those findings were no surprise since multiple myeloma is the second-most common hematological cancer in the US, and experts don't know whether there's any link between the illnesses and toxins released during the disaster.

But Dr. Jacqueline Moline, of the Mount Sinai School of Medicine, says the median age of diagnosis for that cancer is 71 years old, and there should not be so many cases in younger people.

Doctors who coordinated the study said people who worked at the site should continue to have their health monitored.

The study is published today in the Journal of Occupational and Environmental Medicine.
