乳腺癌是女性常见恶性肿瘤之一,是全球女性最常见的肿瘤和首要的肿瘤死亡原因[1]。其发病率近年来在世界范围内呈逐年上升的趋势,但在不同国家和地区之间存在着差异。流行病学研究发现中国、日本及一些亚洲国家的乳腺癌发病率较美国及欧洲国家低[2],生态和移民研究显示这种差异很大程度上是因为环境因素的改变引起,如饮食习惯等[3]。众多的科学家通过人群或动物实验发现了饮食结构中可能对乳腺癌有影
Breast cancer is one of the most common malignant tumors in women and is the most common tumor and the leading cause of cancer death in women worldwide [1]. Its incidence in recent years in the world showed a rising trend year by year, but there are differences in different countries and regions. Epidemiological studies have found that the incidence of breast cancer in China, Japan and some Asian countries is lower than that in the United States and European countries [2]. Ecological and immigration studies show that this difference is largely due to changes in environmental factors such as dietary habits [3]. Numerous scientists found that the diet may have implications for breast cancer through population or animal experiments
