Although the current research is limited to test-tube and animal studies, there is some evidence that flaxseed oil may help reduce the growth of cancer cells.
In a 2015 animal study, mice were given 0.3 ml of flaxseed oil for 40 days. It was found to prevent the spread of cancer and the growth of lung tumors
In an older small animal study, flaxseed oil was shown to block the formation of colon cancer in rats
Furthermore, test-tube studies have produced similar findings, with several studies showing that flaxseed oil reduced the growth of breast cancer cells
Still, while these findings are promising, more research is needed to determine how these results may translate to humans.
