What are they Symptoms and causes of Pancreatic Cancer
As is the case with many cancers, symptoms of pancreatic cancer are shared with those of many other illnesses. Symptoms often do not appear until the cancer has advanced to a late stage; they include abdominal pain, unexplained weight loss, problems with sugar metabolism, and difficulty digesting fatty foods. As a pancreatic tumour grows, it may block the common bile duct, which leads to a buildup of bilirubin in the blood and causes jaundice (a yellowing of the skin and eyes). Blockage of the bile duct may also cause the gallbladder to become enlarged.
The causes of pancreatic cancer vary and in many cases remain unknown. However, several factors have been identified that increase the risk of developing pancreatic cancer. Smoking is the most controllable risk factor, and up to 30 percent of pancreatic tumours have been linked to cigarette smoking. A diet high in animal products, particularly animal fat, also increases cancer risk. In addition, exposure to certain dyes, pesticides, and petroleum products may increase the probability of developing pancreatic cancer. Uncontrollable risk factors include age, sex—males are 30 percent more likely to develop cancers of the pancreas than are females—and illnesses such as diabetes mellitus and chronic pancreatitis. Some cases of pancreatic cancer are clearly the result of inherited defects, while other cases appear to stem from random or environmental causes.
