Officials originally left cancer off the list of covered ills, citing a lack of scientific evidence linking exposure to the toxic fumes at the World Trade Center site to any cancers.
While the new findings suggest at least certain cancers are increased among workers, Ward and Crane also emphasized the brighter side: "The study results are reassuring that there does not appear to be a large increase of cancer in WTC-exposed populations at this time," Ward said.
"It's important to remember that most of these people are not going to develop cancer," Crane said.
He also noted that people exposed to the disaster site can take steps to reduce their cancer risks. "Do not smoke. Eat a healthy diet. Folks should keep doing what they can to maintain a healthy lifestyle."
