MANHATTAN - Two new studies released today failed to connect cancer to exposure to dust from working at Ground Zero, and the findings could potentially affect whether first responder cancer patients can receive funding for medical bills caused by their work at Ground Zero.

An FDNY study of 9,000 Ground Zero firefighters found 25 more cancer cases than average, and experts say the increase could have been caused by chance alone. However, the FDNY's chief medical officer disputes the findings, saying the 19 percent increase in cancer cases is significant and clearly shows a link between Ground Zero dust exposure and cancer.

The second study found that people exposed to Ground Zero dust had a lower overall death rate than the average New Yorker.
