Pancreatic adenomas are not the same as pancreatic cancer. Pancreatic adenomas, also known as pancreatic tumors, include both benign and malignant tumors. Benign tumors include islet cell tumors, pancreatic adenomas, pancreatic fibromas, lipomas, cystadenomas, and solid pseudopapillary tumors of the pancreas. The most common malignant tumors are adenocarcinomas derived from pancreatic ductal cells; other rare ones include pancreatic sarcomas, and neuroendocrine malignant tumors that occur in the pancreas. In addition, there are benign tumors that have the potential to become cancerous or are considered to be a precancerous lesion, such as pancreatic mucinous cystadenoma. Thus, pancreatic tumors include pancreatic cancer, which is only one type of pancreatic tumor. Benign pancreatic tumors can be followed up regularly for observation, and if benign tumors with a tendency to become cancerous are detected, then surgical treatment should also be considered in a timely manner. Surgery is the first choice for diagnosed pancreatic cancer. If surgery is not possible, radiotherapy or targeted drug therapy can also be considered.
