The researchers reviewed 21 different independent prospective cohort studies, they found that a high intake of fish and marine n-3 polyunsaturated fatty acids was associated with a 14 percent reduced risk of breast cancer.

Breast cancer is a form of cancer that develops from breast cells. It is one of the most common cancers, responsible for nearly a quarter of all cancer cases and 14% of cancer deaths in 2008. More than 200,000 women are diagnosed with the disease each year.
THE DETAILS: Researchers looked at non-vitamin, non-mineral "specialty" supplement use of more than 35,000 postmenopausal women and discovered that those who regularly used fish oil supplements were one-third less likely to develop breast cancer than those who did not use fish oil. "We looked at days per week and years of use, but not dose per day," says study author Emily White, PhD, an investigator at the Fred Hutchinson Cancer Center and professor of epidemiology at the University of Washington, both in Seattle. She noted that most women who used fish oil at the time they entered the study (in the low-risk group) took it four to seven times a week.
"Risk of breast cancer did not vary by years of use," she added. Researchers also found a lower breast cancer risk in higher-risk women (older age, obesity, heavy drinking, and physical inactivity are believed to put women at a higher risk) who reported taking fish oil supplements.
