多数人认为，胰腺癌比乳腺癌或前列腺癌的危险性要小，其原因是患该病的人数不多，但事实上胰腺癌具有更大的危险性，多数胰腺癌患者在被确诊之前癌细胞已经转移，因此，大约500名患者中只有一人还可选择外科手术治疗，半数患者在被确诊之后6个星期内死亡，超过五年的生存率不 Most people think that the risk of pancreatic cancer is smaller than that of breast or prostate cancer. The reason is that the number of people suffering from this disease is small. However, in fact, pancreatic cancer is more dangerous. Most patients with pancreatic cancer have cancer before they are diagnosed. The cells have already metastasized. Therefore, only one out of about 500 patients can choose surgical treatment. Half of the patients die within 6 weeks after being diagnosed. The survival rate is not longer than five years.
