Eating a diet high in flaxseeds can assist in lowering the risk of death from breast cancer by 40 per cent.
These are the findings of a new study from the German Cancer Research Centre in Heidelberg.
The research discovered that foods, such as, vegetables, seeds and wheat have special plant compounds, known as phytoestrogens, which kill off cancer cells and keep secondary tumours at bay by preventing the growth of new blood vessels.
The most important phytoestrogen is called lignans, found in abundance in flaxseeds.
In the human body, these phytoestrogens cling on to the female sex hormone oestrogen and are considered to combat cancer.
For the purposes of the study, the researchers analysed blood samples of more than 1,000 women diagnosed with premenopausal breast cancer over a three year duration.
Women who had higher levels of enterolactone in their blood had their risk of death drastically reduced by two fifths compared to women with the lowest levels of tis substance.
The results also highlighted that high levels of enterolactone protect against cancer and secondary tumours spreading.
