About 2500 people were killed during September 11, 2001 mishap as the New York city had to bear over 400,000 tons of asbestos that blew into the air.

The Manhattan Twin Towers were attacked by terrorists.

Mesothelioma cancer was something that first responders and fleeing survivors might experience or have already experienced.

The number of people who survived on the unfateful day was about 111,000 and these lucky survivors might still be in danger, the Mesothelioma Applied Research Foundation, stated.

Those who face the risk of getting this cancer are bystanders, firefighters, first responders and fleeing survivors and many of these people might still be unaware of the possible cancer risks.

Due to high usage of asbestos used for making the World Trade Center fireproof and installed for its insulation, it was declared a hazardous pollutant in 1971.

Ground Zero survivors have suffered from a double tragedy as not only they saw the towers collapse, also they face the risk of mesothelioma cancer.

Dr. David J. Prezant, the chief medical officer for the New York Fire Department, who led the study said, "The findings indicate an increased likelihood for the development of any type of cancer. But he said the results were far from conclusive. This is not an epidemic."
