More evidence firefighters risk cancer from 9/11 exposure
"Our study shows that exposure to the World Trade Center could be a risk factor for the development of multiple myeloma and its precursor disease," the team wrote in the JAMA Oncology report published in the Journal of the American Medical Association

" The median age of multiple myeloma diagnosis was 57 years, which is about 12 years younger than what is seen at the national level, "they added.
They also found that more men than expected had a precancerous disease called monoclonal gammopathy of undetermined significance (MGUS), which may progress to myeloma.
But Dr. Otis Brawley of the American Cancer Society was careful to accept too much of the findings.
"These trials, because of size o In the cohort, one can not detect a small increase in cancer risk due to exposure of the World Trade Center, and correlation does not mean causation," Brawley wrote in a commentary.
"Perhaps this problem is beyond the confines of science."
The same team found out in 2011 that firefighters had a higher risk of cancer – helping them to answer a question that had been fought in the courts for years as a first responder Compensation and care for the aftermath of the disaster sought.
"We wanted to find early, predictive cancer signs that would allow us to screen people and monitor those at risk, by demonstrating MGUS, which predicts the development of multiple myeloma "We are capable of doing that," said Dr. David Prezant of the Albert Einstein College of Medicine, who has contributed to the study.
"Screening for Multiple Myeloma Risk Through Testing For MGUS, we can offer these first responders something that makes this study important."
They found 16 multiple myeloma firefighters, which is about 1.8 times more than a similar population White Men in Rochester, Minnesota
Researchers also analyzed cancer cases among firefighters, compared them to similar New Yorkers, and projected how many more cases of cancer could be expected.

"We expect the FDNY-WTCHP cohort to experience a greater cancer burden than would be expected from a demographically similar population" , the researchers write.  "This underlines the importance of cancer screening and routine screening among WTC-exposed rescue and rescue workers."
It was not a big increase – projected 2,714 cases among white male firefighters, compared to 2,596 for similar white
"Those who have done work on the WTC website may become involved in WTC dust because of their exposure to carcinogens have increased risk for prostate cancer, thyroid cancer and melanoma, "the researchers wrote.
It was widely expected that first responders and survivors of seizures might have a higher risk of cancer.
"Many WTC first responders were initially exposed to aerosolized dust and toxic fumes from the burning of kerosene and building materials," the researchers wrote.
This dust contained powdered cement, glass fibers, asbestos, lead, carcinogenic compounds, polycyclic aromatic hydroxcarbons or PAHs, polychlorinated biphenyls or PCBs, polychlorinated furans and dioxins.
"For the next 10 months of rescue, recovery and cleanup, responders were exposed to burning underground fires that released trapped gases and dust until the end of December," the researchers wrote.
"The latest insult included by-products of diesel fuel burning used by heavy equipment at the site.
The dust and chemicals could also cause chronic inflammation, which can cause cancer, they said.
Brawley said that there is one natural answer is to think so, but he is not convinced by the numbers in the studies.
"The WTC attack is an emotional issue. Cancer is also an emotional issue, "he wrote.
" There is a tendency to want to diagnose something for every cancer. We often attribute cancer to a certain environmental impact. If these WTC heroes are diagnosed with cancer, even a common cancer, there is a natural tendency to assume that this is due to their service to the WTC.
But Brawley said the first responders deserved respect. "They should also be compensated for all injuries related to their ministry and receive the best possible care," he wrote.
Nearly 70,000 responders are in the World Trade In the 9/11 attacks, the attacks enrolled nearly 3,000 people, including more than 400 firefighters and other first responders.
The researchers said all of these people would need to continue with care be monitored and said the program must keep funding at a level that could supply them]
