Excerpts from thechiefleader.com:

Under legislation pending in Albany (NY), city firefighters would be granted a five-year post-retirement period in which they could revise their retirement option if they developed cancer that may be linked to carcinogens they were exposed to on the job.

Epidemiological studies have established the firefighting-cancer link for several years. A 2013 study published in the Journal of Occupational Environmental Medicine, based on the review of the health records of 30,000 firefighters from Chicago, Philadelphia and San Francisco, found “evidence of a relation between firefighting and cancer” and a new finding that found evidence of “excess malignant mesothelioma” as well.

Since 2002, cancer was the cause in almost two out of every three firefighter line-of-duty deaths, according to the International Association of Fire Fighters.

Also included would be any WTC firefighter who developed cancer subsequently but was told by officials that they developed it too soon after 9/11 to claim it was job-related under the Zadroga Act.

The U.S. Centers for Disease Control and Prevention cited formaldehyde, asbestos, and arsenic as problematic.
