Islet cell tumors mostly occur in the tail and body of the pancreas, most of them are single, and only a few are multiple. Tumors vary in size, with an average diameter of about 1-2 cm. The quality is slightly hard, round, red or purple. Pancreatic islet cell tumors are composed of tumor cells similar to pancreatic islet cells, and are separated by connective tissue. About 4/5 cases are benign. The tumor body has a complete envelope and is clearly distinguished from the surrounding boundary. Malignant patients only account for 1/5, and metastases to nearby lymph nodes and liver can occur early.

　　Approximately 20％ islets Cell tumors, which cause hypoglycemia due to excessive insulin secretion. But hypoglycemia is not proportional to the tumor. Long-term low blood sugar can cause symptoms of insufficient blood sugar supply to the central nervous system. Therefore, patients on fasting, especially before breakfast or after strenuous labor, often show symptoms of insulin shock, such as fatigue, confusion, and even delirium, convulsions, and coma. At the time of onset, the blood sugar is usually below 50 mg. If the oral or intravenous glucose solution is taken immediately, the above symptoms will quickly disappear, and such patients often cause obesity due to the prevention of hypoglycemia, multiple meals, and oral sugar .

　　 There are the following treatment methods:

　　 1. Radiotherapy for pancreatic cancer. Three-dimensional conformal radiotherapy is a new technology in the treatment of pancreatic cancer. This method greatly reduces the damage of normal tissues to radiation and protects the liver and kidneys. The principle of dose adjustment is 75%.

　　 2. Endocrine therapy for pancreatic cancer. It is currently believed that estrogen receptors are present in pancreatic cancer tissues and normal tissue cells. Therefore, reports on the treatment of pancreatic cancer with endocrine hormones are increasing. The most commonly used drug is tamoxifen.

　　 3. Surgical treatment of pancreatic cancer. Surgical treatment methods include expanded pancreatic cancer radical surgery and pancreatic cancer combined with organ resection. The former includes regional pancreaticoduodenectomy and regional pancreatectomy, the latter is mainly applicable to pancreatic cancer cases with infiltration of adjacent tissues. The purpose of surgical treatment of pancreatic cancer is to eradicate the tumor, reduce the patient''s suffering, improve the patient''s quality of life, and prolong the patient''s life.

　　 4. Traditional Chinese medicine treatment of pancreatic cancer. Traditional Chinese medicine methods for pancreatic cancer include single prescription, acupuncture, massage, topical application, etc. It can be used in conjunction with surgery, radiotherapy and chemotherapy, aiming to increase efficacy and reduce toxicity, promote the recovery of patients'' physical functions, and improve the quality of life.
