Among the most serious conditions linked to toxic exposure in the aftermath of the terrorist attacks on the World Trade Center (WTC) is multiple myeloma, a rare but aggressive blood cancer that affects plasma cells.
For many first responders, volunteers, office workers, residents, students, and others who were present in lower Manhattan on or after the attacks, a diagnosis of multiple myeloma is directly tied to exposure to the toxic dust that blanketed lower Manhattan and the surrounding areas released when the towers fell.
Could 9/11 exposure be the cause? What scientific evidence supports the connection? And what health care and compensation options are available? This guide explores what we know about the direct link between 9/11 exposure and multiple myeloma, who is at risk, and what medical treatment, support, and compensation are available.
