A Houston firefighter who died due to multiple myeloma in 2017 has been denied her benefits. Margaret Roberts, a Houston firefighter for 21 years was diagnosed with myeloma in 2013. Her doctor stated that she developed the cancer while serving the city as a firefighter. Scientific studies in 1983, 2001, 2006 and 2015 all suggest an “increased” or “significantly elevated” risk for firefighters getting multiple myeloma.
