MINEOLA - A new report says thousands of men and women who worked at Ground Zero have developed cancer.

The report by the World Trade Center Health Program found that more than 2,500 workers and responders developed different forms of cancer from the dust and carcinogens dispersed by the collapsed towers. The number is 20 percent higher than the rate that the WTC Health Program anticipated.

Dr. Marc Wilkenfield cares for Sept. 11 responders at Winthrop University Hospital in Mineola. He says he is not surprised in the increase in patients, and he expects the trend to continue. "Cancer takes time to develop," he said. "This is just the tip of the ice berg."

Government funding set aside to help Sept. 11 cancer patients will run out by 2016. At that point, it will be up to Congress to reauthorize funding.
