硒(Se)主要以硒半胱氨酸形式存在于蛋白质中,是红细胞谷胱甘肽过氧化物酶(GSH—Px)的组成成份,是人体生命活动所必需的微量元素。一、硒与癌症发生的关系缺硒可能会使癌症发病率升高。施劳泽等计算了28个国家和地区居民微量元素饮食摄入量与癌症的相关性,发现各类癌症与硒呈负相关。低硒地区及血硒低的人群中以消化道癌(食道癌、肝癌、结肠癌)及乳腺癌发病率为高。于树玉等发现肝癌的地区分布与肝癌高发
Selenium (Se) is mainly in the form of selenomethionine in the protein, is a component of erythrocyte glutathione peroxidase (GSH-Px), and is a trace element necessary for human life and activity. First, the relationship between selenium and cancer Selenium may increase the incidence of cancer. Shi Laze et al. Calculated the dietary intake of trace elements in 28 countries and regions and the correlation between cancer and found that various types of cancer were negatively correlated with selenium. Low selenium areas and low blood selenium in people with gastrointestinal cancer (esophageal cancer, liver cancer, colon cancer) and breast cancer incidence is high. Yu Shuyu and other areas found in the distribution of liver cancer and liver cancer
