Pancreatic cancer is a serious disease characterized by the abnormal and uncontrolled growth of cells in the pancreas. This uncontrolled growth can disrupt the organ's normal functioning, leading to various symptoms. Common signs include dark urine, pale stools, nausea, vomiting, abdominal bloating, indigestion, loss of appetite, and the new onset or worsening of diabetes.

The pancreas has two main functions: exocrine and endocrine. The exocrine pancreas secretes enzymes (pancreatic juice) into the small intestine, which aid in the digestion of nutrients; this breaks down carbohydrates, proteins, and fats, converting them into energy. The endocrine pancreas produces hormones like insulin and glucagon, regulating blood sugar levels. Pancreatic cancer can adversely affect these vital functions, leading to devastating consequences for overall body health.
