乳腺癌是西方社会及美国妇女最常见的肿瘤之一。其发病率在过去五年里由十万分之87增至104。目前公认早期诊断与治疗对乳癌预后较好。尽管目前推广乳腺自检等,死亡率并不下降。很明显,目前迫切需要一种敏感、可靠、可行的早期乳癌识别方法。特殊的生长因子可刺激DNA的合成并促进细胞分裂,它们在肿瘤发生中的作用正在被阐明。 Breast cancer is one of the most common tumors in Western societies and American women. Its incidence has increased from 87/100,000 to 104 in the past five years. It is currently recognized that early diagnosis and treatment have a better prognosis for breast cancer. Although the current promotion of breast self-test, etc., the mortality rate does not decline. Obviously, there is an urgent need for a sensitive, reliable and feasible early breast cancer identification method. Specific growth factors stimulate the synthesis of DNA and promote cell division. Their role in tumorigenesis is being elucidated.
