Flaxseed intake linked to lower breast cancer risk

Thursday Oct 30, 2013 (foodconsumer.org) -- A new Canadian study in Cancer Causes & Control suggests that eating flaxseed can help reduce the risk of breast cancer - a disease that is diagnosed in 300,000 women and kills 37000 each year in the United States.
The study led by C Elizabeth and colleagues found eating flaxseed or flaxseed bread associated with 18 or 23 % reduced risk of breast cancer.  None of 19 factors that may potentially affect the risk were actually identified as confounders for the correlation between flaxseed intake and risk of breast cancer.

Flaxseed contains high levels of dietary lignans - a class of phytoestrogens.  Eating foods with phytoestrogens like soy foods have been associated with reduced risk of breast cancer.  The current study was believed to be the first to report the association between flaxseed alone with risk of breast cancer.

The study compared 2999 women diagnosed with breast cancer 3370 healthy women enrolled in the Ontario Women's Diet and Health Study for their consumption of flaxseed.

The study indicates that eating flaxseed may help prevent breast cancer.  Flaxseed is available in local health stores or over the internet as a healthful food.  Flaxseed is also available as a dietary supplement.  Numerous studies have linked eating soy foods to reduced risk of breast cancer.

Breast cancer is in many cases a preventable disease.  An authoritative organization suggests that two absolutely certain risk factors are hormone replacement therapy and ionizing radiation, which is unfortunately also used in mammography - the machine used to screen breast cancer. (David Liu)
