Pancreatic cancer is a serious disease characterized by the uncontrolled growth of abnormal cells in the pancreatic tissues. This type of cancer often does not show distinct symptoms in its early stages. However, common signs that may appear include jaundice, darkening of urine, clay-colored or pale and greasy stools, itchy skin, loss of appetite and unexplained weight loss, abdominal or back pain, nausea, vomiting, and elevated blood sugar levels.
