Fish oil boosts responses to breast cancer drug tamoxifen.

Omega-3 fish oil was shown to boost the effectiveness of tamoxifen in a rat model of breast cancer.  The oil seemed to boost the activity of gene associated with cell differentiation, a sign of decreased aggressiveness for cancer cells.  The oil also increased the expression of genes related to immune responses against cancers.  The results were presented at the annual AACR onference.
