Pancreatic Cancer: 7 Warning Signs Including Diabetes After 50 And Unexplained Weight Loss
Seven symptoms that may warrant evaluation for pancreatic cancer.
Pancreatic cancer can be difficult to identify in its early stages because its symptoms may be mild, nonspecific or similar to those caused by more common conditions. Gastroenterologist Dr Saurabh Sethi has highlighted seven potential warning signs, including new-onset diabetes after 50, unexplained weight loss, changes in stools, persistent back pain and jaundice. Awareness of such changes can help people seek medical evaluation when symptoms persist or occur together.
The pancreas is located in the upper abdomen behind the stomach and has important roles in both digestion and blood-sugar regulation. It produces insulin as well as digestive enzymes that help the body process food. Pancreatic cancer develops when abnormal cells in the pancreas grow uncontrollably and form a tumour. Exocrine pancreatic cancers are the most common type, while pancreatic neuroendocrine tumours arise from different cells.
One warning sign highlighted by Dr Sethi is developing diabetes after the age of 50 without an obvious explanation. Changes in pancreatic function can affect insulin production and blood-sugar regulation. Another potential sign is unexplained weight loss despite no intentional changes to diet or exercise. Pancreatic disease can interfere with digestion and nutrient absorption, although these symptoms can also have many causes unrelated to cancer.

Changes in bowel movements may also warrant attention, particularly pale, oily or floating stools, which can occur when the body has difficulty digesting fats. Persistent, dull pain in the middle of the back without an apparent injury is another symptom Dr Sethi highlighted, as problems involving the pancreas can sometimes cause pain that radiates toward the back. However, these symptoms are not specific to pancreatic cancer and may occur with other digestive or musculoskeletal conditions.
Yellowing of the skin or eyes, known as jaundice, is another possible warning sign, particularly when a tumour affects bile flow. Dr Sethi also highlighted sudden intolerance to familiar foods, including new nausea, reduced appetite or an unexpected aversion to foods that were previously well tolerated. Persistent itching without an identifiable skin condition may also occur when problems with bile flow lead to a buildup of bile-related substances in the bloodstream.
The presence of any one of these symptoms does not mean a person has pancreatic cancer, and several have numerous possible explanations. However, persistent or unexplained changes, particularly when multiple symptoms occur together, should be discussed with a healthcare professional. Early medical assessment can help determine the underlying cause and whether further testing is necessary.
