The phytochemical properties of EOAm were determined by gas chromatography-mass spectrometry (GC-MS) and the ameliorative effect on breast cancer was demonstrated by histological findings and biochemical markers, such as serum malondialdehyde (MDA), serum reduced glutathione (GSH), and serum vascular endothelial growth factor (VEGF) in female rats. This evidence concerns the gene VEGFA and breast cancer.
