乳腺癌病因学研究进展

乳腺癌的发病原因复杂,至今尚不能用已知的单因素或多因素模型来完全解释其发生机制与发展过程.流行病学研究提示,生活环境的恶化、生活方式与膳食结构的改变等仍是主要原因,了解乳腺癌已知的病因或高危因素,有利于乳腺癌的预防和早期诊断,针对高危人群的筛查和干预性治疗已经使乳腺癌的发病率与死亡率降低.

Advances in research of etiology of breast cancer

The etiopathogenisis of breast cancer is very complex, its pathogenesis and development can not be completely elucidated by one-factor or multiple-factor model Epidemiologic studies indicate that deterio-ration of environment,changing of life style and dietary pattern and so on are common factors. It is of great sig-nificance to comprehend some known factors and high-risk factors which is helpful to prevention and early diag-nosis of breast cancer. The incidence and the mortality of breast cancer have fallen down due to screening and prophylactic therapy for high-risk population.
