Pancreatic tumor 5cm first identify benign malignant, suspected malignant tumor according to the pathology of pancreatic tumor typing, the presence of near or distant metastasis and so on to determine. At present, only through the size of the tumor can not determine the staging. 1. Pathologic typing: Pancreatic cancer is clinically classified into 6 types, including adenocarcinoma, small gland carcinoma, ductal adenocarcinoma, small cell carcinoma, etc. Different types have different treatments, and the clinical prognosis is also somewhat different. 2. Near or distant metastasis: malignant tumors of pancreas mainly undergo TNM staging, T refers to the growth of the tumor, which is initially evaluated according to the growth size of the tumor, N refers to the presence of metastasis of the lymph nodes in the near area, and M refers to the presence of distant metastasis. A simple pancreatic malignant tumor 5cm in size without regional lymph node metastasis or distant organ metastasis usually belongs to the intermediate stage. However, the presence of distant metastasis suggests that it has entered the advanced stage. If pancreatic tumor is suspected or diagnosed, it is recommended to go to regular hospitals for comprehensive assessment of the condition and follow the doctor’s instructions for treatment to avoid delaying the condition.
