7. Weight loss
Obviously, if you are having trouble eating, you lose weight. But more than decreased appetite may be at play if pancreatic cancer is involved.
Tumor-induced weight loss, also known as cancer cachexia, changes the way the body uses calories and protein. More calories than normal are burned, the body begins to break down muscle protein, and appetite is suppressed.
Pancreatic tumors also release cytokines into the blood which cause the body to burn more calories than are replaced. If you have lost more than 5% of your body weight within about six months, with no known reason, check in with your doctor.
