Further research needed to draw conclusive connection between cancer and Ground Zero

Outrage was sparked Tuesday in response to a federal report that concluded that there is not enough evidence yet to say whether the dust and smoke cloud produced by the terrorist attack on the World Trade Center caused cancer.

Yesterday, Kiran Chetry spoke with John Feal, a demolition supervisor at Ground Zero who founded the FealGood Foundation to help 9/11 first responders, who called the study a "slap in the face."

This morning, Dr. Jacqueline Moline from the North Shore-LIJ Health System, joins American Morning to discuss the findings and to comment on her own study, which is the only one to date that has suggested a link between cancer and 9/11 responders.

Despite the fact that Dr. Moline believes there is a connection between cancer and exposure to Ground Zero, she stresses that it will take time and further research before the connection can be conclusively drawn scientifically.
