Pancreatic cancer is one of the most aggressive tumors known, and the most effective treatment method is surgery. The surgery to be performed depends on the location of the tumor in the pancreas. Tumors in the tail of the pancreas require surgery, including removing that part of the pancreas and the spleen. In tumors in the head of the pancreas, a more comprehensive surgery will include the duodenum, part of the stomach, bile ducts, and gall bladder (Whipple operation). In large tumors, it may be necessary to remove the entire pancreas. In this case, since the enzymes involved in digestion and insulin-regulating blood sugar become defective, the patient may present with several related complaints. Therefore, patients need additional treatments after such surgeries to control blood sugar or ease digestion.
