Cancer rates rising for Ground Zero first responders

NEW YORK (NEWSCHANNEL 3) - Cancer rates among first responders and rescuers who rushed to Ground Zero are rising.

The New York Post reports cases have doubled in the last year.

There are now 2,500 certified cases of cancer among the more than 37,000 World Trade Center workers and rescuers who have been screened.

Cancer researchers claim there is no significant correlation.

A doctor with the American Cancer Society says cancer rates among firefighters are typically higher.
