A pancreatic tumor is an abnormal growth of cells in the pancreas, an organ located behind the stomach responsible for producing digestive enzymes and hormones like insulin. These tumors can be benign (non-cancerous) or malignant (cancerous), with pancreatic cancer being one of the most aggressive and challenging to treat. Symptoms often include abdominal pain, weight loss, jaundice, and new-onset diabetes. Early detection is crucial for improving prognosis, though it remains difficult due to the organ's deep location and non-specific early symptoms.
