Most people may not understand how aggressive pancreatic cancer is. In our country, the incidence of pancreatic cancer has increased significantly compared to 20 years ago. Once pancreatic cancer is diagnosed, only 10% to 15% of patients have the chance of surgical resection, and less than 10% of them can be cured. The 5-year survival rate of pancreatic cancer patients is only about 5%. How to detect pancreatic cancer as early as possible? Abdominal pain, weight loss and jaundice are the most common symptoms of pancreatic cancer. Abdominal pain can be present, and the typical pain sites are middle and upper abdomen and lower left chest. The pain is mild at the beginning and gradually worsens later. Early on, the pain is dull and vague, but later it may develop into colic and continuous pain. The abdominal pain is usually more pronounced at night and when lying on the back. Weight loss is a very important symptom of pancreatic cancer. 90% of patients have rapid and significant weight loss, and some patients do not have abdominal pain or jaundice. About 70% of patients develop jaundice at some point in the course of the disease, which is usually accompanied by diarrhea, constipation and abdominal distension. Based on the above symptoms, it is important to be alert for the following conditions. Specific painful areas that are not clearly stated and can radiate to the lower back, while the gastrointestinal examination is normal. Unexplained weight loss. Unexplained recurrent episodes of pancreatic abdominitis, which manifests as severe upper abdominal and involves pain in the lower back, nausea, vomiting, high fever and even jaundice. Those who are over 40 years old, usually eat more fatty and meat foods, smoke for many years, and then have the above mentioned conditions, should go to the hospital for examination in order to detect pancreatic cancer as early as possible. Important note Sudden onset of diabetes, but not obese, and no one in the family has diabetes should also be alert because pancreatic cancer can also be combined with diabetes. What are the main treatment options for pancreatic cancer? The main treatment for pancreatic cancer is surgical resection, but the 5-year survival rate after surgical treatment is less than 5%. For example, radiation therapy can be administered before surgery to make the surgical treatment more effective.
