A pancreatic neuroendocrine tumor (PNET) is a rare type of cancer that originates in the hormone-producing cells of the pancreas. Unlike more common pancreatic cancers, PNETs can be functional, meaning they may produce hormones that affect bodily functions, or non-functional, which do not produce hormones. Symptoms can vary based on hormone production and tumor size. Diagnosis typically involves imaging tests like CT scans or MRI, along with blood tests to check hormone levels. Treatment options may include surgery, targeted therapy, or chemotherapy, depending on the tumor's characteristics and stage. Early detection can improve outcomes for patients.
