Breast Cancer

Our research has shown that omega-3 fatty acids can incorporate into the developing mammary gland of the mice. This is relevant because the alteration of cellular membrane phospholipid composition may influence the functionality of proteins involved in cell growth, tissue structure and long term breast cancer risk. Overall, lifelong exposure of omega-3 fatty acids in a novel transgenic mouse model of breast cancer was causally linked to reduced tumour size and numbers. These lines of evidence demonstrate the importance of omega-3 fatty acids throughout life for mitigating and preventing breast cancer.
