Pancreas cancer is so hard to treat, so can we remove it altogether?

Depends on stage. Not all patients with pancreatic cancer are candidates for surgical removal, also called resection. The best candidates for resection are patients whose cancer has not spread beyond the pancreas, who have no involvement of the major abdominal blood vessels, and are otherwise healthy enough to tolerate a major abdominal operation. Sometimes chemoradiation therapy is used prior to the operation.
Sometimes. Despite the gloomy statistics, a small minority of resections for truly localized pancreatic cancer result in a cure. The most important way you can optimize your result is to seek treatment at a high volume center from a multidisciplinary team that works on delivering multiple types of treatment in a coordinated fashion.
