The Atlantic Wire notes a recent study, which has the “first substantive findings that show working at Ground Zero increased cancer risks.”

Rebecca Greenfield highlights findings from other studies on health-related impacts:

• Stress response to the attacks has been associated with a 53 percent increased incidence of cardiovascular issues, a study three years after 9/11 found. 
• Caring for those emotionally affected by the terrorist attacks led to compassion fatigue according to research out of the International Journal of Emergent Mental Health. 
• Following the event, a study concluded an upward trend in post-traumatic stress disorder, even for those who did not directly experience the event, another found. 
• Those who were exposed to World Trade Center aftermath report constant headaches. 
• About 8.4% of office workers and 8.6% of passersby developed asthma 5 to 6 years after the attacks.
