Asbestos Exposure May Increase Risk Of Colorectal Cancer

Asbestos Exposure May Increase Risk Of Colorectal Cancer
Exposure to asbestos is well know to cause mesothelioma, and it has been a long contentious issue if asbestos causes increased risk of colorectal cancer as well. Latest research shows evidence that this may be the case.

Dr. Cullen and associates used data from a cancer prevention trial to investigate the risk of colorectal cancer among nearly 4000 men. These patients were put into two subgroups, one with history of exposure to asbestos and the other without any history of exposure. The researchers have found that men in the asbestos exposed group were 36 percent more likely to develop colorectal cancer compared to those who were not exposed to asbestos.

The researchers have published their finding in the recent issue of American Journal of Epidemiology. Persons who had heavy exposure to asbestos had even higher risk of developing colorectal cancer. People with 21 to 30 years of exposure to asbestos had a 74 percent increased risk of colorectal cancer compared with those with less than 10 years of exposure. The age at first exposure to asbestos was not predictive of the risk of colorectal cancer.

Researchers are recommending aggressive screening for colorectal cancer in those who have exposure to asbestos.
