Pancreatic cancer is a type of malignant tumor that has seen an increase in incidence in recent years. The early symptoms and signs of pancreatic cancer include the following: many patients experience abdominal pain, which often radiates to the shoulder and back. Additionally, some patients with early-stage pancreatic cancer may develop jaundice in the skin and mucous membranes, and some may even exhibit bleeding spots. Moreover, some patients with early-stage pancreatic cancer may show symptoms of indigestion, experiencing repeated belching, nausea, and loss of appetite. Furthermore, the symptoms of early-stage pancreatic cancer are generally not typical because the tumor is located deep within the body and is small, hence it does not invade surrounding tissues. Therefore, the clinical symptoms are neither severe nor diverse.
