People who developed cancer after being exposed to the toxic ash that was dispersed over Manhattan when the World Trade Center (WTC) collapsed on 9 September 2001 would qualify for free treatment of the disease and potentially hefty compensation payments under a rule proposed by US federal health officials. They say 50 different types of cancer should be added to the list of sicknesses covered by a $4.3 billion fund set up to compensate and treat people exposed to the toxic smoke, dust and fumes in the months after the incident.
