Too Much Fish Oil Might Boost Prostate Cancer Risk, Study Says

Eating a lot of oily fish or taking potent fish oil supplements may increase a man's risk of developing prostate cancer, new research suggests. Moreover, marine sources of omega-3 fatty acids may also raise the risk for aggressive prostate cancer, according to the study by scientists at the Fred Hutchinson Cancer Research Center in Seattle. "These anti-inflammatory omega-3s were associated with a 43 percent increased risk for prostate cancer overall, and a 71 percent increased risk in aggressive prostate cancer," said study lead author Theodore Brasky, a research assistant professor at Ohio State University Comprehensive Cancer Center in Columbus, who was at Hutchinson at the time of the study. Aggressive prostate cancer is often fatal, he added. http://www.nlm.nih.gov/medlineplus/news/fullstory_138583.html
